What is more harmful, marijuana or alcohol? Why?
To begin with, it is necessary to say that we do not consider alcohol harmful – it is not alcohol that kills, but its quantity. And this applies to everything: not food leads to obesity, but food amount. And in this factor, of course, alcohol is much more harmful, because, unlike marijuana, it leads to addiction – this is the first. The second: with large doses of consumption, again, alcohol is much more harmful.
The remaining factors can be listed for a long, really long time: Alcohol is toxic, and marijuana is not. Alcohol causes physical dependence, and marijuana does not. It is rather difficult to find a comparable parameter which would allow to say that marijuana is more harmful than alcohol.
The inability to metabolize alcohol as quickly as it enters the body can lead to alcohol accumulation in the brain and the “shutdown” of its vital areas, in particular, those responsible for heartbeat and breathing. Thus, one can die from drinking in five minutes from the beginning of alcohol drinking. This has never happened with marijuana! Of course, marijuana has an effect on the cardiovascular system, increasing heartbeats and blood pressure, but a person cannot exceed a single dosage up to fatal, as it happens with alcohol!
Besides, hemp derivatives can be used as drugs, but alcohol cannot. And the most funny thing is: Alcoholism and even drug addiction can be treated by cannabis (link to the “Alcoholism” encyclopedia section), but to treat drug addiction by alcohol is a bit strange, isn’t it? Therefore, all questions regarding “what is more harmful” should disappear on their own.
