You REALLY cant blame your problems on weed. If you know you cant study when stoned, then dont get stoned. Doesnt mean it's the weed. It's like people saying weed makes them lazy - and i say BULLSHIT. People make themselves lazy, and blame weed. Coz if you blame it on the weed, it's not your fault is it? It's just shifting the blame. Sorry if this seems harsh, but it's true. It's your problem, from you. Not from the weed.
