I have been researching CBD oil which is a derivative of hemp. Hemp is not psychotropic because it has extremely low or non existant levels of THC in it. The oil comes in different strengths and you have to adjust accordingly to see what strength you need. I just ordered some to try in my vaper cigarette and it has no nicotine or other harsh chemical additives. Some come with a flavor or without or even seperated, oil in one vial flavor in the other vial.
Hemp is not illegal and anyone can purchase it.
