Ive seen how someone may fuck up their lives by doing hard drugs like heroine and cocaine but i dont really see how someone can fuck up their lives by smoking......its not physically addictive...if anything people dont get addicted...they just get depandant,....meaning its all in your brain...I think for the people who fuck up their lives smoking you really need to revalulate your whole situation....marijuana isnt the type of drug to "fuck up your life" dont blame the weed for fucking up your life, blame it on yourself.
