Cannabis DOES ALTER The Brain- The Younger One Starts, The GREATER Risk Of SERIOUS Damage Done!

The folks who want you to believe that smoking weed is actually a healthy thing for you to do, that it does less damage than alcohol, etc.?

Tell ’em they’re high. And they don’t know what they’re talking about.

Weed is not good for you.

Cannabis has long-term effects on a person’s brain – especially if they start using the drug earlier in life, according to a new study.

Starting to use marijuana before the age of 16 has been found to result in an underdeveloped prefrontal cortex, scientists revealed.

That’s the part of the brain responsible for judgment, reason and complex thinking.

In contrast, people who start to use marijuana after the age of 16 experience accelerated brain aging.

Lead study author Dr Francesca Filbey, of the University of Texas at Dallas, said: ‘Not only did age of use impact the brain changes but the amount of cannabis used also influenced the extent of altered brain maturation.’

A team of researchers from the university’s Center for BrainHealth analyzed MRI scans of 42 heavy marijuana users.

Each of the participants were between the ages of 21 and 50, and indicated that they began using cannabis in adolescence.

All of the participants continued to use marijuana through adulthood – using the drug at least one time each week.

Twenty of the study’s participants were categorized as early onset users – with a mean starting age of nearly 14.

Additionally, 22 of the participants were found to be late onset users – with a mean starting age of nearly 17.

Typically, in adolescent brain development, the brain prunes neurons – resulting in reduced cortical thickness, as well as a greater amount of gray and white matter contrast.

Pruning usually leads to increased gyrification – the addition of wrinkles or folds on the surface of the brain.

Through MRI scans, the scientists determined that the more marijuana consumed by early onset users, the greater their cortical thickness.

Additionally, early onset users were also found to have less gray and white matter contrast, and a less intricate gyrification.

The scientists said these findings indicate that when the participants began using marijuana before age 16, their brain experienced arrested development in the prefrontal cortex.

As for those who started using marijuana after age 16, they were found to have brain changes that normally occur later in life.

Science says smoking weed will inhibit your ability to reason, and prevent you from exercising good judgement or work through complex problems. In other words, it’ll turn you into a stoner.

Is that what you want for yourself?
