Despite what efforts to legalize and popular culture wants you to believe, it's a verified and scientific proven fact that marijuana can be an addictive substance which can cause both acute and long-term physical and mental injury to users. Similar to other substances, a person who has used marijuana for a prolonged time period can become addicted to its effects and can experience withdrawal symptoms whenever they abruptly quit using marijuana. Users today have very high grade marijuana available which wasn't the case two decades ago, which makes it an even larger issue.

Somebody that uses marijuana on a regular basis is significantly altering how the brain functions, hence the brain can't just automatically return to normal operation when the person ceases using marijuana, this may take 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 can be a challenge for long-term users, because users will encounter withdrawal symptoms which are often difficult to endure. These symptoms may not be as physical in nature as heroin withdrawal for example, but marijuana detox and withdrawal may cause severe depression along with other psychological symptoms for chronic users. This is why relapse is so prevalent for those who try and cease using marijuana by themselves. Marijuana detox services can be obtained at alcohol and drug detoxification and drug and alcohol rehab programs in Oakland to help individuals through this course of action so they don't relapse and may obtain further rehab services after detoxification.
