I've been smoking about a gram a day for a few months (once a day/multiple times a week for months prior) and my lungs don't give me much trouble, I walk far distances daily and don't really get shortness of breath or anything.
Im lazy, but i've always been that way and I doubt the cannabis makes it much worse.

My memory sure is funny, I can remember things that are important enough to me though it is somewhat hard to remember things that I am told throughout the day. My memories of the past few weeks are vague, I couldn't tell what happened monday from what happened wednesday but if somebody brings something up I may be able to remember it in more detail.
I do not believe in have in any way harmed my brain, my math skills are as good as they've always been, I understand algebra and physics just fine. I was never great at speaking to people but still find writing to be pretty easy. However in verbal communication between peers I find myself often having to say "wait so what the hell have you been telling me about for the past five minutes?"

I am however hundreds of dollars in debt and really need to find a job or some sort of motivation.
