Cannabis is an herb containing over 500 chemicals, including THC, a mind-altering compound that causes harmful physical and psychological effects. The fact that cannabis has been legalized or decriminalized in many states contributes to the mistaken belief that cannabis is completely safe. Cannabis addiction can present itself in many ways. It is a mental obsession to either have or be using the drug. Long-term usage of the drug can lead to needing cannabis everyday, loss of motivation, relying on the drug to cope with stress, financial difficulties, aggression and wanting to stop but being unable to do so. Often times, users or addicts may find themselves using alone, or begin selling the drug illegally.
