The title is a bit much but I tried to get your attention 
My questions are for cocaine and a bit of weed, If you can answer my questions I would be very grateful
How long does the high last?
I had just under 4 grams of coke (I didn't think it was that great stuff and It may have been mixed with speed). Is it possible that I may OD? (I have only done it a couple times before - Cocaine a few times and Weed EVERYDAY)
Would more weed help me come down?
I feel great should I take more or wait to cool down?
I don't know what to do know, I just looked up info on cocaine and found this website, Please HELP
I am kind of worried that I will fall asleep and never wake up since I read on this page that people have overdosed on just a couple of grams
It was not the greatest stuff and if any of you know brazil, I brought it in a favela
