Despite what efforts to legalize and today's culture would lead you to think, it is a verified and conclusive fact that marijuana can be an addictive substance which can bring about 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 will become dependent on its effects and will encounter withdrawal symptoms should they initially quit using marijuana. Users today have extremely high grade marijuana at their disposal which wasn't the situation 10-20 years ago, which makes it an even larger problem.

Somebody that uses marijuana frequently is significantly altering how the brain functions, hence the brain can't just instantly readjust to normal operation as soon as the person 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 a challenge for long-term users, because users will encounter withdrawal symptoms that may be difficult to endure. These symptoms may not be as physical as it is with heroin withdrawal as an example, but marijuana detox and withdrawal might cause severe depression as well as other mental symptoms for long-term users. For this reason relapse is so common for those who try to stop using marijuana by themselves. Marijuana detox services are offered at drug detoxification and drug rehab centers in Nelson to help people through this process so they don't relapse and may receive further treatment services after detox.
