If you want more couch-lock from a meds-batch, you can decarboxylate the buds by putting them in a oven-proof and airtight container and 'baking' them for half an hour @ 122C/252F. What this does is first convert THCA to THC (this normally happens during smoking/vaping) and if you continue, it will convert most THC to CBN.

Nice share .....but i have a question about decarbing the weed for more of a couchlock........if by vaping or smoking the weed you stated that it decarbs then......if you do it in the oven first and then smoke or vape it wont you lose some of the potency.....now this is just my thinking but what happens to the decarbed bud when it is smoked or vaped....since essentially you are decarbing it twice? not trying to step on your toes.....just that was new to me......King John did tell me to decarb it before making butter, but hadnt heard to increase couch lock......hopefully my question makes sense PlanetJlol
