In spite of what efforts to legalize and popular culture would lead you to think, it is a proven and scientific fact that marijuana can be an addictive substance which can cause both short and long-term physical and mental injury to users. Like other substances, a person who has used marijuana for an extended time period can become addicted to its effects and can encounter withdrawal symptoms should they initially stop using marijuana. Users today have very high grade marijuana at their disposal which wasn't true two decades ago, making it an even bigger problem.

Someone that uses marijuana on a regular basis is really changing the way the brain functions, so the brain can't just instantly readjust to normal function once the person stops using marijuana, this will take some time. Individuals actually detox from marijuana, like every other drug, as the drug is eliminated from the body and the body readjusts to function without marijuana. So marijuana detox is usually a challenge for habitual users, because users will encounter withdrawal symptoms that may be difficult to endure. These symptoms may not be as physical in nature as heroin withdrawal for instance, but marijuana detox and withdrawal may cause extreme depression and other psychological symptoms for long-term users. This is why relapse is so prevalent for those who try and quit using marijuana on their own. Marijuana detox solutions can be found at drug and alcohol detoxification and drug and alcohol rehabilitation programs in Havana to help individuals through this process so they don't relapse and can receive further treatment services after detoxification.
