It’s important to exercise caution and make informed decisions about substance use to minimize potential risks and harms. Whether marijuana is more addictive than alcohol is a complex question, and there’s no simple answer. There’s no doubt marijuana can help people.
Epidemiology of marijuana smoking and road traffic accidents
However, both substances are known to have negative impacts on health, and both have addiction potential. While both substances carry a potential for misuse and addiction, it appears to be more common with alcohol. While some people may have a very low tolerance for weed, they may be able to tolerate alcohol well. Secondly, there is a suggested link between cannabis use and psychosis, with an increased risk of psychotic outcomes, especially with frequent use. Firstly, regular cannabis use may increase the risk of developing social anxiety disorder, with heavy users more likely to report thoughts of suicide. Excessive drinking has been linked to an increased risk of dementia and other mental health problems, such as depression and anxiety.
An average search uses only 0.3 watt-hours of electricity, so all global searches are only 12.5 million watts or 5% of the total electricity consumption by Google. Total carbon emissions for 2010 were just under 1.5 million metric tons, mostly due to fossil fuels that provide electricity for the data centers. In October 2006, the company announced plans to install thousands of solar panels on its Mountain View campus to provide up to 1.6 Megawatt of electricity, enough to satisfy approximately 30% of the campus’ energy needs. The company’s fourth cable, named Grace Hopper, connects landing points in New York (US), Bude (UK) and Bilbao (Spain), and is expected to become operational in 2022. In September 2025 Google opened their £735m AI Centre in Waltham Cross, Hertfordshire and announced their plans for £5 bn investment in AI research, in the same month that Alphabet reached market capitalisation of $3 trillion.
Two simulator studies showed that the tendency to overtake was decreased with cannabis use but increased with alcohol.52, 53 One simulator study and two on-road studies examining car-following behavior concluded that cannabis smokers tend to increase the distance between themselves and the car in front of them.41, 45 Other studies have found no adverse effects of marijuana use on sign detection,49 a sudden lane-changing task,43 or the detection of and response to hazardous events.48 Alcohol also reduces the perceived negative consequences of risk-taking,31 which can increase willingness to take risks after drinking,32 the amount of risk-taking behavior while driving, even at low alcohol doses,33 and the incidence of road traffic accidents while driving drunk.34, 35 However, there is considerable variability in the effects that alcohol can have on people—the same dose may have different effects not only on different individuals, but also in the same individual on different occasions, because of other factors such as gender, body mass index, age, drinking habits, time of day, stomach contents, genetics, stage of the menstrual cycle, and environmental factors.36 While weed may have fewer long-term risks than alcohol, the lack of extensive research on cannabis makes it challenging to draw definitive conclusions. Because of these difficulties, epidemiological studies have also shown inconsistent effects, some finding decreased or no risk from driving while smoking marijuana, and others increased risk. As far back as 1970, Reese Jones noticed that alcohol’s effects were diminished in heavy cannabis smokers.61 A subsequent study showed that regular cannabis smokers demonstrate less of a decrement in peripheral signal detection under the influence of alcohol than do infrequent users,62 and a later study still found that regular cannabis users given alcohol alone showed less of a decrement in tracking accuracy and dizziness ratings than infrequent users given the same alcohol dose.63 The reason for this is unclear, but is hypothesized to result from either pharmacological or behavioral cross-tolerance between marijuana and alcohol. The rising prevalence of cannabis use, its increased availability and potency,5 lower prices, widespread social tolerance, and earlier age of onset of use have combined to increase the number of users and hence the number of people subject to cannabis use disorders.6 Peak initiation is at age 18, and ten years later, 8% of users are marijuana-dependent.7 Most cannabis use is intermittent and time-limited, however; users generally stop in their mid-to-late 20s, and only a small minority continue in daily use over a period of years.8
How Addictive Is Alcohol?
In July 2013, Google introduced the Chromecast dongle, which allows users to stream content from their smartphones to televisions. Google Earth, launched in 2005, allows users to see high-definition satellite pictures from all over the world for free through a client software downloaded to their computers. A job search product has also existed since before 2017, Google for Jobs is an enhanced search feature that aggregates listings from job boards and career sites.
Treatment Options for Marijuana Abuse
The National Highway Transportation Safety Administration (NHTSA) reported that in 25% of all motor vehicle crash fatalities, the driver had a blood alcohol concentration (BAC) of 0.01 g/dL (one eighth the legal limit) or greater, and in 21-year-old drivers, that figure rose to 39%.12 Drivers with a previous DWI (“Driving While Impaired”) conviction were responsible for 7.2% of all crashes involving alcohol. As marijuana is the most commonly used drug of abuse, having been tried by 40% of the population,3 and is also smoked most commonly in the age group that also has the most road traffic accidents, the contribution of marijuana smoking to road traffic accidents is of great concern to both governments and clinicians responsible for counseling patients with substance abuse problems. Accidents are the fifth leading cause of death in the US; nearly half are motor vehicle accidents, which according to the Fatality Analysis Reporting System (FARS) killed 38,588 people in 2006 alone.1 Motor vehicle accidents are the nation’s leading cause of death in those under 30.2 The contribution of drugs of abuse to this accident rate has attracted increasing attention in recent years because of the dramatic increase in drug use. Drunk drivers are involved in 25% of motor vehicle fatalities, and many accidents involve drivers who test positive for cannabis. It can also cause slowed motor skills and, if smoked, exposure to marijuana smoke and other chemicals can lead to emphysema.
Alcohol’s impact on brain health
- While conventional search engines ranked results by counting how many times the search terms appeared on the page, they theorized about a better system that analyzed the relationships among websites.
- Alcohol and weed (cannabis) are two unique substances that produce different effects, making a side-by-side comparison difficult.
- Google also hosts Google Books, which allows users to search books in its database and shows limited previews, or the full book when allowed.
- Mixing alcohol and weed can also increase the likelihood of engaging in risky behaviors.
- Meanwhile, the so-called “Catch me up” tool will provide users with reminders of their upcoming events and appointments.
- However, this is low compared to 40% of all car crashes that directly involve alcohol.
In response, Google threatened to close off access to its search engine in Australia. Such measures included slowing down hiring for the remainder of 2020, except for a small number of strategic areas, recalibrating the focus and pace of investments in areas like data centers and machines, and non-business essential marketing and travel. Later in 2019, some workers accused the company of retaliating against internal activists. On November 1, 2018, more than 20,000 Google employees and contractors staged a global walk-out to protest the company’s handling of sexual harassment complaints. The company subsequently announced that “48 employees have been fired over the last two years” for sexual misconduct. Google CEO Sundar Pichai accused Damore of violating company policy by “advancing harmful gender stereotypes in our workplace”, and he was fired on the same day.
THE EFFECT OF CANNABIS COMPARED WITH ALCOHOL ON DRIVING
Cannabis and alcohol acutely impair several driving-related skills in a dose-related fashion, but the effects of cannabis vary more between individuals than they do with alcohol because of tolerance, differences in smoking technique, and different absorptions of Δ9-tetrahydrocannabinol (THC), the active ingredient in marijuana. On the other hand, weed can also impair cognitive abilities and reflexes, and excessive use may lead to cannabis use disorder and potential health risks. While there is limited research on the topic, animal studies suggest that chronic cannabis consumption may produce cross-tolerance for the impairing effects of alcohol.
It may feel like almost everyone you know drinks alcohol. No matter how safe a substance seems, addiction is always possible. Alcohol and marijuana use are both socially acceptable, and they can both be dangerous. Her work explores post-traumatic growth and the drug addiction substance use disorder diagnosis and treatment connection between physical and mental health.

Some people are choosing to replace alcohol with weed, and experts commend the trend of questioning one’s relationship with alcohol. While alcohol has been linked to approximately 88,000 deaths per year, according to the CDC, the effects of cannabis are harder to quantify due to its illegal status in many places. Cannabis can also affect brain development and brain aging, with some studies showing a link between long-term heavy cannabis use and decreased IQ points. The long-term effects of cannabis are less well understood due to how to hide nicotine from drug dogs a lack of research. Alcohol can also affect brain health and cognitive abilities, with studies showing reduced grey matter and compromised white matter in the brains of drinkers.
Alcohol and cannabis affect the brain differently, but they share a similar target
- But it’s up to you to decide if marijuana products will benefit you in the long run.
- Research indicates fundamental differences in addiction mechanisms and prevalence.
- On September 14, 2022, Google lost the appeal of a €4.125 billion (£3.5 billion) fine, which was ruled to be paid after it was proved by the European Commission that Google forced Android phone-makers to carry Google’s search and web browser apps.
- While alcohol has been linked to approximately 88,000 deaths per year, according to the CDC, the effects of cannabis are harder to quantify due to its illegal status in many places.
- In contrast, “we don’t see any statistically significant effects of cannabis on gray matter or white matter,” Hutchison said.
- Weed has been linked to an increased risk of heart problems, including heart attacks, heart rhythm issues, and heart failure.
Additionally, alcohol can contribute to cardiovascular issues, including high blood pressure, irregular heart rhythms, and an increased risk of stroke. Over time, the brain can become dependent on alcohol to release dopamine, leading to tolerance, where the individual needs to consume increasingly larger amounts to achieve the same effect. However, when it comes to addiction and the potential for life-destructive consequences, alcohol poses a greater threat than cannabis. Specifically, alcohol abuse represented 0.6 years of accelerated brain ageing, a significant but less pronounced effect compared to cannabis abuse, which resulted in 2.8 years of premature ageing.
It is important to note that there is a lack of large-scale, long-term studies on the health effects of cannabis, especially in comparison to alcohol. As the legalization of cannabis expands, more people are turning to weed as a substitute for alcohol, with daily cannabis use surpassing daily alcohol consumption for the first time. Barker notes alcohol can also impact numerous other organ systems in the body, from minor effects, like dehydrating our skin, to more dramatic health risks, such as causing inflammation in the pancreas, or pancreatitis.
Alcohol is more widely used than weed, and its negative effects are, therefore, more far-reaching. Cross-tolerance between alcohol and weed has been documented in laboratory animals, but it is unknown whether cross-tolerance develops in humans. Alcohol and weed affect the brain differently, but they share a similar target called the dopamine reward system. Furthermore, the combination of alcohol and weed can make it harder to gauge one’s level of intoxication, especially when weed is consumed before alcohol. However, the presence of alcohol can selectively potentiate the effects of THC on divided attention tasks. However, it is important to note that supportive data in humans is scarce, and the existing studies have produced conflicting results.
While conventional search engines ranked results by counting how many times the search terms appeared on the page, they theorized about a better system that analyzed the relationships among websites. The company has received criticism involving issues such as privacy concerns, tax avoidance, censorship, search neutrality, antitrust, and abuse of its monopoly position. All of these purchases were part of Google’s effort to expand from its search engine business into advertising by combining the various firms’ databases narcissistic alcoholic mother of information in order to tailor ads to consumers’ individual preferences. In 2023, Alphabet took in $175 billion in revenue (57% of all Google revenue) from advertising based on users’ search requests.
Cannabis is more likely to lead to a use disorder where you are habitually or are psychologically addicted to cannabis and want to use it. This can require you to seek medical treatment to come clean. Prolonged alcohol use can lead to physical dependence, where the body becomes reliant on alcohol to function normally.This can cause the shakes and can affect your ability to lead a normal life.
