Yes, you can illegally sell marijuana. Most drug dealers are caught so there is not a good chance for you to successfully sell marijuana without being caught.
you either bag it up into dime bags, or nickle bags, or you sell weight. as in a quarter ounce, half ounce, and so on and so forth. dimes go for $10 nickles for $5 and a quart ounce starts at $35....
Many people sell marijuana. No one will realy give there name, so it is not certain who. If you are asking this question to get drugs, then please seek help.
weed is technically legal for medical uses in NJ but they have not set up a prescription system so you cannot legally obtain a prescription for marijuana in the state of NJ so the answer is no
