Sinsemilla (sin-seh-me-yah; it’s a Spanish word), hashish (“hash” for short), and hash oil are stronger forms of marijuana.
All forms of marijuana are mind-altering (psychoactive). 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 it’s strength or potency, which is related to the amount of THC it contains(5). The THC content of marijuana has been increasing since the 1970s. For the year 2006, most marijuana contained, on average, 7 percent THC.
