Alcohol can be extremely dangerous, if one is drinking and driving. I don't think you can say the same for tobacco and marijuana.
Marijuana and tobacco are natural substances found in nature. Alcohol has to be made through a fermentation process.
But apparently alcohol is not forbidden...and marijuana is.
I mean...here nobody goes to jail for selling vodka to middle-schoolers.
But if you sell marijuana to them...yes, you're jailed.
I wonder why...
