In spite of what efforts to legalize and today's culture would lead you to believe, it is a proven and conclusive undeniable fact that marijuana is an addictive drug which may cause both acute and long-term physical and psychological injury to users. Similar to other drugs, a person who has used marijuana for an extended period of time will become dependent on its effects and can experience withdrawal symptoms if they initially quit using marijuana. Users today have very high grade marijuana at their disposal which wasn't the situation two decades ago, making it a much larger problem.

Someone that uses marijuana regularly is really changing the way the brain functions, therefore the brain can't just automatically readjust to normal function when the person stops using marijuana, this may take some time. People actually detox from marijuana, like any other drug, as marijuana is eliminated from the body and the body readjusts to normal operation without marijuana. So marijuana detox could be a challenge for habitual users, because users will experience withdrawal symptoms which are often difficult to endure. These symptoms might not be as physical as it is with heroin withdrawal for instance, but marijuana detox and withdrawal can cause severe depression and other psychological symptoms for long-term users. For this reason relapse is so prevalent for those who try to cease using marijuana by themselves. Marijuana detox services are available at drug and alcohol detox and drug and alcohol rehab programs in Waterloo to help individuals through this process so that they don't relapse and can receive further rehabilitation services after detoxification.
