Additionally, the potency of marijuana has increased significantly since the 1970s, when this specific chemical substance first gained rampant popularity. Many strains of marijuana are extremely potent, and when coupled with new and innovative methods of ingesting – such as vaping – the potency is increased even further. In recent years, cases of marijuana abuse and addiction have increased along with marijuana-related emergency room visits. The Drug Abuse Warning Network reported that in the year 2011 alone there were close to 456,000 emergency room visits directly related to marijuana throughout the country.
When an individual smokes marijuana (or used the drug in any other form), chemicals like THC enter the bloodstream through the lungs and eventually make their way to the brain. Many individuals who use marijuana will experience feelings of relaxation and euphoria, which can make the substance psychologically addictive. If marijuana is used regularly, the individual will begin to build up a tolerance, meaning more of the substance is required in order for the same psychological effects to be produced. Once a tolerance develops it is not unlikely for symptoms associated with marijuana withdrawal to occur with abruptly ceased use. These are only two of many signs and symptoms that go hand-in-hand with marijuana abuse and addiction.
