lightweight... lmao kidding (half) anyway what you smoked was some of the good shit man just enjoy it and dont question the high.. i've had my "is this laced?" moments as well but then i realize that no dealer would b stupid enough to lose money by putting other drugs in there and sometimes depending on the mndstate youre in, weed can take you for a huge spin im pretty sure it also had to do with the fact you pulled an all nighter.. you already had the "all nighter high" to go along with it..
