I don't think thats the point, SOME people drink to get drunk or to drastically alter their state of mind EVERYONE who is doing LSD is doing it to drastically Alter their state of mind.
And no one is saying Alcohol isn't more damaging physically but the mental and psychological effects more than make up for it so the chart sayig Alcohol is damaging is pointless. people get druck in kill their cheating wife people do too much LSD and kill the monster coming right for them... or at least what they thought was a monster
they get violent and can rarely be talked down because their mind is in a different realm or reality.
