Don't worry, it's highly unlikely that it was laced since this isn't cost effective for dealers, given how cheap Cannabis is in comparison to other drugs, and dispensaries too will always ensure quality.

A lot of people have bad experiences when they have a low tolerance and smoke a large amount. You have to get used to the high before you can go smoking way more than usual, as otherwise it can really scare you.

As for an overdose, you would have to consume around 32 ounces, that's 896 grams, or 1792 joints, in the space of about 15 minutes to even have a *chance* of overdosing. In terms of overdose potential Cannabis is probably the safest plant on earth. This is also with zero tolerance, so with a low or basic tolerance the number of joints would probably double, and good luck smoking that much in such a short time.

To put it short, you just got really high, but don't worry about it, next time will be more pleasant. If it isn't, you can sue me. :thumbsup:
