Black Market Weed is Marijuana that has not been tested for purity and contamination. This weed is sold illegally through dealers. Legalization now organizes a way for patients to have access to a dispensary or pharmacy to buy high-grade medical Cannabis. Weed bought on the street has no label, purity standards or contamination test results in print. Black Market Weed may contain heavy metals, pesticides, bacteria, mold or other harmful contaminants.
