- Facts on Marijuana and Alcohol -

Alcohol use contributes to reckless behavior and serious injuries, and it is highly associated with emergency room visits, whereas marijuana use does not contribute to such behavior and injuries, and is seldomly associated with emergency room visits.
 

Marijuana is far less toxic and less addictive than alcohol.

Alcohol is one of the most toxic drugs, and using just 10 times what one would use to get the desired effect can lead to death. Marijuana is one of – if not the – least toxic drugs, requiring thousands of times the dose one would use to get the desired effect to lead to death.   This “thousands of times” is actually theoretical, since there has never been a recorded case of marijuana overdose.

There are hundreds of alcohol overdose deaths each year, yet there has never been a marijuana overdose death in history.  The consumption of alcohol is also the direct cause of tens of thousands of deaths in the U.S. each year.

In 2001, there were 331 alcohol overdose deaths and 0 marijuana overdose deaths. Source: U.S. Centers for Disease Control (CDC). Source: http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5337a2.htm

Long-term marijuana use is far less damaging than long-term alcohol use.

Excessive alcohol consumption is the third leading preventable cause of death in the United States and is associated with multiple adverse health consequences, including liver cirrhosis, various cancers, unintentional injuries, and violence.

Whereas, the U.S. Centers for Disease Control has no reports of "marijuana-induced deaths", they reported 20,687 “alcohol-induced deaths” (excluding accidents and homicides) in 2003.  Source: http://www.cdc.gov/nchs/fastats/alcohol.htm

Moreover, there is little evidence that long-term cannabis use causes permanent cognitive impairment, nor is there is any clear cause and effect relationship to explain the psychosocial associations.

There are some physical health risks, particularly the possibility of damage to the airways in cannabis smokers. Overall, by comparison with other drugs used mainly for ‘recreational’ purposes, cannabis could be rated a relatively safe drug. Source: Iversen, Leslie. Current Opinion in Pharmacology.

The latest and most comprehensive research on marijuana has concluded that it does not contribute to the development of lung cancer. Source: http://www.washingtonpost.com/wp-dyn/content/article/2006/05/25/AR200605...

There has never been a documented case of lung cancer in a marijuana-only smoker, and recent studies find that marijuana use is not associated with any type of cancer. The same cannot be said for alcohol, which has been found to contribute to a variety of long-term negative health effects, including cancers and cirrhosis of the liver.

Alcohol use contributes to aggressive behavior and acts of violence, whereas marijuana use reduces the likelihood of violent behavior.

Alcohol is clearly the drug with the most evidence to support a direct intoxication-violence relationship.

Alcohol use is highly associated with violent crime, whereas marijuana use is not.

About 3 million violent crimes occur each year in which victims perceive the offender to have been drinking at the time of the offense.

Two-thirds of victims who suffered violence by an intimate (a current or former spouse, boyfriend, or girlfriend) reported that alcohol had been a factor.

Among spouse victims, 3 out of 4 incidents were reported to have involved an offender who had been drinking. Source: U.S. Department of Justice. Bureau of Justice Statistics. National Crime Victimization Survey 2002.

Alcohol use contributes to the likelihood of domestic violence and sexual assault and marijuana use does not.

Of the psychoactive substances examined, among individuals who were chronic partner abusers, the use of alcohol and cocaine was associated with significant increases in the daily likelihood of male-to-female physical aggression; cannabis and opiates were not significantly associated with an increased likelihood of male partner violence.

…the odds of any male-to-female physical aggression were more than 8 times (11 times) higher on days when men drank than on days of no alcohol consumption. The odds of severe male-to-female physical aggression were more than 11 times (11 times) higher on days of men’s drinking than on days of no drinking. Moreover, in both samples, over 60% of all episodes occurred within 2 hours of drinking by the male partner. Source: Fals-Stewart, William, James Golden, Julie A. Schumacher.

Alcohol use is prevalent in cases of sexual assault and date rape, whereas marijuana use is not considered a contributing factor in cases of sexual assault and date rape.

A Harvard School of Public Heath study found that 72 percent of college rapes occurred when the female was too intoxicated by alcohol to resist/consent.  Source: http://www.hsph.harvard.edu/cas/Documents/rapeintox-pressRelease/

Comparisons between alcohol and marijuana with respect to sexual assault are very difficult.  This is because it does not appear as if marijuana is a significant contributing factor.  The best way to "prove" this is through observation that many organizations dedicated to studying and educating about sexual assault do not list marijuana as a substance associated with incidents.  Here is a good example from the Rape, Abuse & Incest National Network:  http://www.rainn.org/get-information/types-of-sexual-assault/drug-facilitated-as...

They note that alcohol "remains the most commonly used chemical in crimes of sexual assault."  Given the fact that marijuana is easily accessible and used widely in social interactions, it is quite telling that marijuana is not even listed at all on this "Drug Facilitated Assault" page.

Another example:  A Web site sponsored by the U.S. Dept. of Health and Human Services lists alcohol, but not marijuana, as putting a person at risk for unwanted sexual activity: http://www.womenshealth.gov/faq/date-rape-drugs.cfm

Alcohol use contributes to reckless behavior and serious injuries, and it is highly associated with emergency room visits, whereas marijuana use does not contribute to such behavior and injuries, and is seldomly associated with emergency room visits.

Lifetime use of marijuana is rarely associated with emergency room visits.  According to an analysis of epidemiologic survey data, “[M]arijuana was by far the most commonly used (illicit) drug, but individuals who used marijuana had a low prevalence of drug-related ED visits."  Source: American Journal of Emergency Medicine, July 12, 2010.

"Alcohol use in the six hours prior to injury was associated with [an elevated] relative risk compared with no alcohol use. Cannabis use was inversely related to risk of injury." Source: BMC Public Health, 2009. http://www.biomedcentral.com/1471-2458/9/40

“Self-reported marijuana use in the previous seven days was associated … with a substantially decreased risk of injury.”  Source: University of Missouri Dept. of Medicine, June 2006.

"Alcohol and cocaine use is independently associated with violence-related injuries, whereas opiate use is independently associated with nonviolent injuries and burns. ... Associations of positive toxicology test results for ... cannabis ... with injury type, injury mechanisms, and outcomes were not statistically significant."

Fewer than 200 total patients were admitted to California hospitals in 2008 for “marijuana abuse or dependence.” By contrast, there are an estimated 73,000 annual hospitalizations in California related to the use of alcohol.
