Yesterday I was smoking 2 joints with two friends of mine, i was having a good time (a was a bit nervous too ) but then i threw up. before smoking i had a snack. It was my second time smoking it. (I also don't know if i was really high) The first time nothing happend. What i want to mention too is that smoke nicotine cigarettes rarely and one time like one month ago i puked too. ( before smoking I had a headache too so it might be that ) SO WHAT ARE THE REASONS ? Nervousness? Did i smoke too much? Am i allergic? The tobacco?
