English to Italian Art/Literary Other droghe

In una festa di adolescenti, un ragazzo chiede a una ragazza:

‘Blowback?’ He asks, waving a joint at me.
I nod and he turns the joint around in his mouth and carefully places it between his lips, waiting until I come closer, opening my mouth to suck in the smoke.

Per l'appunto trovo che blowback vuol dire "To hold a marijuana joint in ones mouth between the lips with the hot end in the mouth while blowing smoke out of the hole at the other end into someone else's mouth, so as to get a big 'hit' ", ma non ho idea della traduzione in italiano
