Marijuana smoking at early ages causes height impairment and an early on-set of puberty for regular smokers.
According to a new study conducted in Pakistan at the PMAS-Arid Agriculture University Rawalpindi, boys who were described as ‘marijuana addicts’ were 4.6 inches shorter, as well as 9 pounds lighter by the age of 20 than their non-smoking peers.
The results of the study were presented at the European Congress of Endocrinology, Dublin as the study focused on hormone release for both groups under analysis.
The research was conducted on a pool of 437 young boys. They were divided in two groups. The cannabis-addicted group counted 220 subjects. The non-smokers group counted 217 subjects. In both groups height, weight, as well as the levels of testosterone, luteinizing hormone, cortisol and growth hormone were compared.
Plasma concentration of the cortisol and luteinizing hormone, as well as that of testosterone was significantly higher for the boys who were regular users of cannabis. Growth hormone levels were found to be low.
The combination of factors indicated that puberty sets off earlier in the regular cannabis-smoking group, while growth is hampered. Cortisol, also known as the stress hormone, presenting high levels of concentration in the blood, sets the stage for a stressed body that enters into early adulthood, creating a number of problems.
At the same time, Dr. Rivzi, lead of the research brought to light that beyond the medical implication, the issue pinpoint emotional and behavioral development that might be problematic for this group.
As the marijuana addicts enter puberty earlier than their non-smoking peers they are exposed to a very volatile environment with entails the onset of drinking and smoking. Consequently, the level of substance abuse increases significantly as the boys find themselves at an incipient level of emotional maturity, despite their bodies’ reactions.
In Europe, according to the newest data available, the highest number of cannabis use features in the age group from 15 to 25-year olds. Reportedly, it is higher among male than female.
In the U.S., marijuana is undoubtedly the most popular drug of choice among youngster. The 2014 survey from the National Institute on Drug Abuse revealed that 11.7 percent of 8th graders had used cannabis in the last year. Comparatively, 35.1 percent of 12th graders had used it during the past year.
On a daily basis, marijuana use was reported with 1 percent of 8th graders and 6 percent of 12th graders.
