First of all Congrats Bank Robber, that is a huge accomplishment
as for everyone else. i went to school for Alcohol and Other Drug Abuse Counselor and drugs do things to the body and the brain that are not good whether used in moderation or abused. it's the same as alcohol, it kills your liver over time whether drank in moderation or abused. i drink and i know the consequences, alcoholism runs in my family i was an alcoholic at one time, i drank to not feel the pain and i was always drinking. now i have learned to control myself and drink in moderation if i feel like i'm starting to abuse it again, i stop!
in my opinion it is wrong to say that you will never find who you really are if you don't try drugs. i've never touched one illeagal drug in my life and i know exactly who i am. i went through alot of other hard times in my life to realize who i am. i watched my father be addictted to drugs, beat me and i went through emotional abuse from a boyfriend. so to me that showed me who i am and how strong i can be!
as for saying someone who can't control themselves is useless, you are basically saying that when i was an alcoholic my life was useless! and i disagree very much so. everyone in life has a purpose no matter what it is, their life means something.
