Because a tolerance builds up, marijuana can lead users to consume stronger drugs to achieve the same high. When the effects start to wear off, the person may turn to more potent drugs to rid himself of the unwanted conditions that caused him to take marijuana in the first place. Marijuana itself does not lead the person to the other drugs; people take drugs to get rid of unwanted situations or feelings. The drug (marijuana) masks the problem for a time (while the user is high). When the “high” fades, the problem, unwanted condition or situation returns more intensely than before. The user may then turn to stronger drugs since marijuana no longer “works.”
The vast majority of cocaine users (99.9%) began by first using a “gateway drug” like marijuana, cigarettes or alcohol. Of course, not everyone who smokes marijuana and hashish goes on to use harder drugs. Some never do. Others quit using marijuana altogether. But some do turn to harder drugs. One study found that youth (12 to 17 years old) who use marijuana are 85 times more likely to use cocaine than kids who do not use pot, and that 60% of the kids who smoke pot before the age of 15 move on to cocaine.
Marijuana is sometimes combined with harder drugs. Joints are sometimes dipped in PCP, a powerful hallucinogen. PCP is a white powder, also available in liquid form, often used with cannabis. PCP is known for causing violent behavior and creating severe physical reactions including seizures, coma and even death.
