Marijuana comes from the Cannabis plant. It is used as a psychoactive drug and as medicine. Tetrahydrocannabinol or THC is the primary psychoactive ingredient in marijuana. According to the United Nations Office on Drugs and Crime, the potency or THC content of marijuana increased from approximately 3.3 percent in the mid 1980’s to 4.47 percent in the late 1990’s.
Marijuana has been associated with mood shifts or euphoria, relaxation and an increase in appetite. It can also cause short-term memory loss, dry mouth, impaired motor skills, poor concentration, paranoia and anxiety.
Marijuana is currently illegal under federal law. However, the states of Washington and Colorado have recently legalized recreational marijuana use for adults 21 and over. California state law allows the use of marijuana for medical purposes. However, in May 2013, the California Supreme Court ruled that local governments can ban medical marijuana dispensaries. Such bans have been enacted in more than 180 cities throughout California.
A new version of marijuana is known as ‘Wax’ or ‘Budda’. This is a liquid form of marijuana that does not have a smell and can be placed in vaporizers or e-cigarettes.
