Marijuana, hashish (hash) and hash oil come from cannabis sativa, a type of hemp plant. All three contain THC, a chemical that changes the way you think, feel and act. The word “cannabis” is used to refer to all three.
Marijuana is made from the dried leaves and flowering tops of the plant.
At a certain stage in the growth of the plant, before the flowers are mature, they become coated with a sticky resin. The resin can be dried to make hash.
Hemp can also be used to make rope, fabric and paper. When it is grown for this purpose, the amount of THC is too small for someone to use it to get high.
