With marijuana legalization a reality in 23 states and in Washington DC–and an inevitability in many other states–it is poised to become one of two legal intoxicating substances, with alcohol being the other. This brings up the question: which is safer to use…marijuana or alcohol? Both substances actually have their health risks, but the facts as to which one is safer may surprise you.
Keep in mind that these results were involved in subjects who used alcohol or marijuana for several years.
Immediate effects of marijuana:
- Impairs judgment
- Slows down reaction time
- May affect coordination and motor skills
- Increases the risk of accidents
- Causes changes in mood and behavior
Immediate effects of alcohol:

- May affect coordination and motor skills
- Increases the risk of accidents
- Causes changes in mood and behavior

Driving under the influence of alcohol:
- Causes impairment of judgment
- Slows down reaction time
- May affect coordination and motor skills
- Increases the risk of accidents
As you can see, both marijuana and alcohol may cause a number of significant health risks. That being said, alcohol does seem to be slightly riskier than marijuana, which does not discount the risks associated with chronic or long-term marijuana use.
That being said, it should be noted that there remains much research yet to be done on the long-term effects of marijuana use. It is also notable that marijuana–primarily the ingredient cannabadiol (CBD) has been linked to a number of significant health benefits. Again, much research remains to be done with regard to whether or not marijuana is actually a healthy substance. But when you compare it to alcohol–which has proven negative effects and very little health benefits–it would seem that marijuana has the edge over alcohol when it comes to safety and benefits.
