I would go with the first option, most likely. As apache said, lack of money is what usually makes me feel like "fuck it I'm broke anyway why not just spend all I have on drugs so I'll have a few hours of relief?" If I had unlimited money, yeah I might find those "rare to find" drugs every now and then and them.. but with tons of $$$ i wouldn't have as much stress, I wouldn't have to worry about whether or not I can pay rent.. or I could even get my own place and move somewhere lovely, start enjoying life! No financial worries would be a blessing truly.
And maan, that is a bad question for me... 'cause I really hate ice and Ritalin.! Doing either is like a guaranteed panic attack. If I haad to choose, I'd take the Ritalin and try to sell or even give it away.
Soo.. do you personally think that you are a drug addict or have a serious problem, or are you able to stop for long periods of time with no cravings / still a functioning member of society?
