Two years ago I tried taking cough pills with some friends and we did it several times after and now I'm always wanting them. It's like I'm craving the high I get from them. Now there's a law against how old you have to be to buy them. I was wondering is there a similer high that you can legally buy? If so is age limits and things like that?

You won't find anyone here willing to help you with that information.

No it is illegal for a reason, and constant use will cause health problems for you. Please get counseling to get off the addiction.
