Marijuana vs alcohol pro choice would be marijuana Speaking in the sense in which one is healthier for you both can be abused and have negative effects. Having that said the consequences from drinking defer drastically from smoking if you were to abuse alcohol there is a very large potential for death this is supported by the fact that 15'000 people die from alcohol a year and when you are under severe influence of alcohol you are able to sprint around screaming about with no judgement whatsoever. While stated in the pro alcohol section of this debate it is said that marijuana is potentially dangerous for your lungs while there is safe alternates to smoking marijuana not damaging to your lungs ( vaporizing, consumption through infused food) there are no recorded fatal overdoses or marijuana use and when under the influence all you want to do is chill and have a relaxing time with some of you best buds the risk of injury due to 'stupid ideas' is significantly reduced. So in my opinion I think marijuana use is severely less hazardous and lethal making it the less dangerous substance. On a side note going to try a triple front flip of a roof into a pool is way more likely to happen while drunk than high. Are you going to die from chugging a bottle a vodka? Possibly. Are you going to die from chain smoking 11 joints? You'll probably order a pizza and have the best sleep of your life waking up in the morning feeling great rather than having your face in the toilet and feeling like crap the rest of the day.
