Son smoking marijuana 'dwarfed by 10cm'

A new study found that young people who regularly smoke marijuana have a lower and lighter height than those who do not smoke. If smoking before puberty will cause your body to stunt and cause the height to drop more than 10 cm.

According to the Telegraph newspaper, this study also shows that instead of bringing relaxation, smoking cannabis can cause the body to become more stressful for a long time.

"Using marijuana can stimulate stress response, puberty but inhibit growth," said lead researcher Dr. Syed Shakeel Raza Rizvi of Rawalpindi Agricultural University in Pakistan. The team investigated the level of hormones associated with growth and puberty in the blood of 220 non-smokers and 217 marijuana addicts.

Using marijuana can stimulate stress reactions, puberty but inhibit growth.

As a result, hormone levels related to puberty, such as testosterone and gold-stimulating hormone (LH), increase in smokers, but in contrast, the level of growth hormone in this group is reduced.

At the same time, men who do not use heavier marijuana average 4.6 kilograms and 4.6 inches (11.7 cm) higher than 20-year-olds compared to smokers.

Besides, the team also looked at the effects of marijuana on the level of stress hormone - cortisol - and they found that smokers had significantly higher cortisol levels.

Cannabis is the most widely used illegal drug in Europe, estimated to have 80.5 million Europeans used at least once in their lives. In the UK, the rate of 11-15 years of marijuana use has decreased from 13.3% in 2003 to only 7% in 2013, equivalent to about 250,000 people.

The latest report from the European Center for Drug and Drug Monitoring (EMCDDA) shows that the highest rate of age for marijuana use is between 15 and 24, and higher in men.

Previous studies have looked at the effects of marijuana smoking in adult and human rats, but this is the first time the effect has been officially found on men participating in the trial.

Researchers believe that this finding will help us better understand the dangers of drugs for growth and development in children.
