I take for the moment oxycodone and weed from street it s m'y first experience with fresh plant i want to decrease the oxyco and for it i sélect a variety with 1:1 thc cbd around 12℅ i want to extract the best product with the highest yield ..... It s really for médical use....thx un advance for jour tome

If you're using it for medicinal I'd say your best bet would be to do a hash wash then dry that and press it into a live Rosin
