Despite what efforts to legalize and today's culture would lead you to think, it is a proven and scientific proven fact that marijuana is an addictive substance which may cause both acute and long-term physical and psychological harm to users. Much like other drugs, somebody who has used marijuana for a prolonged time period will become dependent on its effects and will encounter withdrawal symptoms should they abruptly quit using marijuana. Users today have extremely high grade marijuana at their disposal which wasn't the situation two decades ago, which makes it a much bigger problem.

Someone that uses marijuana often is significantly changing the way the brain functions, hence the brain can't just instantly readjust to normal function as soon as the individual ceases using marijuana, this will take time. Individuals actually detox from marijuana, like every other drug, as the drug is eliminated from the body and the body readjusts to normal operation without marijuana. So marijuana detox can be quite a challenge for long-term users, because users will experience withdrawal symptoms that may be difficult to endure. These symptoms might not be as physical in nature as heroin withdrawal for example, but marijuana detox and withdrawal may cause severe depression and other psychological symptoms for long-term users. That is why relapse is really prevalent for many who try to quit using marijuana on their own. Marijuana detox services are offered at drug detoxification and drug treatment programs in Oregon to help people through this process so they don't relapse and can receive further rehab services after detoxification.
