Psychedelic mushrooms, usually containing psilocybin. Most commonly encountered form is Psilocybe cubensis. Sold as "hydroponic shrooms" by unscrupulous dealers, not because they are grown hydroponically, because that's not even possible, but because ignorant weedtards will pay more money for them.
Mushroom grower: Want some shrooms?
Dealer: Are they hydroponic shrooms?
Mushroom grower: Of course not, it's not possible to grow mushrooms hydroponically. Which ignorant fucktards have you been speaking to?
Dealer: Sorry man, I'll take the shrooms, but people keep asking me if I can get "hydro shrooms". Are you sure there's no way of doing it?
Mushroom grower: It's just not possible, that's not how mushrooms grow, and even if it was possible, then the mushrooms wouldn't be any stronger. It's like asking for LP records in mp3 format.

Later on in the day:

Dealer: Want some shrooms?
Weedtard: Dude, are they hydroponic shrooms?
Dealer: Yeah, that's why they're $60 per 1/8th.
Weedtard: Hit me with da bomb shit.

Montreal, Canada is now, seemingly in the middle of a real paradoxical condo-shroom, the condo-shroom paradoxically picking up pace despite the legal challenges by The Charbonneau Commission to the spiel of the conscruption-industry.
