Long term potheads that I have had the misfortune of running into were all hopelessly addicted and even electro-shock therapy with cattle-prods wouldn’t keep them away from weed. So yes, pot is addictive and in fact anyone who says it’s not is, well, like the potheads above, who deny being addicted.
Are you still on your anti-marijuana crusade? You are the ‘Dudley Douchebag Drug Warrior’ of the Nanny State and the Prison Planet. It is a damn plant that at its worst makes you lazy and stupid, not violent. For ever marijuana user put in jail there is a murderer, rapist, or violent felon running free. Do you think that the US can afford to lock everyone up? Sod off.
