If you're really interested in smoking again do some research into stealth growing. You can keep 1-2 plants in a very small space. Enough to supply yourself and friends if you wanted. I think this is probably the way the majority of "professionals" smoke as it gives them a hobby, security, and a completely clean product. You'll find a number of threads from older people on here who have problems finding stuff. I'm sure it's just because the age gap makes it hard to fall into the main-stream "stoner scene". Good luck to you and welcome!
