How long do the effects of smoking marijuana and THC last? We break down the effects.

Every year, millions of people consume marijuana in various forms, but by far the most common is inhaling smoke or vapor from the dried plant. Whether it's for recreational or medical purposes, it's important to remember that cannabis affects our bodies on many levels.

Most people who decide to smoke marijuana expect at least one of its effects. It can be the introduction of a euphoric state, but it can also be a therapeutic treatment for anxiety., insomnia or coping with chronic pain. Regardless of the purpose of smoking it, they want to know how long the effects will last and what determines this. That's why we decided to discuss the most important information in this area.

Pharmacokinetics of marijuana

Pharmacokinetics is a branch of pharmacology that studies drugs and medicinal products. It encompasses the processes a drug undergoes from the moment it is administered until its elimination from the body. These processes are most often referred to by the acronym ADME, which stands for absorption (the route of absorption), distribution (the route the drug takes through the body), metabolism, and elimination (the complete clearance of the drug from the body).

This is important because every active substance approved for medicinal use must have this process thoroughly described. Marijuana is no exception, so let's take a closer look at the durability of its effects.

The duration of marijuana's effects depends on the method of administration, so we will discuss smoking and vaporizing, which are considered the fastest-acting, as the first visible effects of its administration occur within a few minutes of the first introduction of smoke/vapor into the lungs.

All of this depends on several factors. Some of these are related to the type of marijuana or the dose taken at one time, while others depend on individual factors. 

It's believed that the most beneficial effects of smoking marijuana occur within 1-3 hours of initial exposure, but the effect can last longer. It's also worth noting that the euphoric peak occurs approximately 30 minutes to 1 hour after consumption. Much depends on how often and in what quantities you consume marijuana.

People who use it sporadically may experience more intense and longer-lasting effects than those who consume marijuana regularly. Individual metabolic factors and interactions with other medications or psychoactive substances, such as alcohol, also play a role, as they can impair the effects of marijuana. 

Research published by Cannabis and Cannabinoid Research (The “Next Day” Effects of Cannabis Use: A Systematic Review) specifies that the effects of smoking marijuana most often last for a maximum of 10 hours, although it mentions that people sensitive to its effects may experience them for up to 24 hours, but these are sporadic situations and require further attention from scientists.
