It's hogwash to say drunkenness is no excuse for crime... Wherever mind altering drugs are on sale to the public, we should expect mind altered behaviour from the public.
The best mind-altering drug is the truth.
Altering your perspective can provide you the luxury of seeing things for what they are, not what you wish them to be.
Drugs are a carnival in hell.
You have power over your mind - not outside events. Realize this, and you will find strength.
