Sinsemilla (sin-seh-me-yah; a Spanish word), hashish ("hash" for short), and hash oil are stronger forms of marijuana.
All forms of marijuana are mind-altering. In other words, they change how the brain works.
They all contain THC (delta-9-tetrahydrocannabinol), the main active chemical in marijuana. They also contain more than 400 other chemicals. Marijuana's effects on the user depend on the strength or potency of the THC it contains. The potency of marijuana has increased since the 1970s but has been about the same since the mid-1980s.
