Alcohol is worse no doubt. But judging which one is more negative doesn't really mean much when in the end both can have negative effects on people.
A lesser of an evil is still an evil.
I shake my head when people say it's harmless. If adults are telling children using weed is harmless then...
Sadly I saw a life long friend's life spiral downwards from the moment he started using cannabis. It turned an outgoing happy person into a dark reclusive type.
For a large amount of people it won't have much of an adverse effect.
For my friend we found him hanging from a rope.
It's nothing...
