Today's teens are less likely to be taking drugs than their predecessors, a survey says.
8th and 10th grade students also reported the most difficulty in actually getting their hands on marijuana since 1992.
A study from the National Institute on Drug Abuse says specifically alcohol abuse among teens is at its lowest level, ever.
What's more, rates of alcohol and tobacco use are also now at their lowest since the survey began. However, there has been a continuous decline in the drug abuse rates throughout the last decade.
Some positive news comes from the youngest participants.
But the research found that high school seniors were still using cannabis at almost the same levels as in 2015, with 22.5 percent saying that had smoked or ingested the drug at least once within the past month and 6 percent reporting daily use. Daily use among eighth graders dropped in 2016 to 0.7 percent from 1.1 percent in 2015.
Only 5% of 8 graders made use of marijuana, while only 10% and 14% of 10 graders and the 12 graders respectively consumed drugs. Among seniors, rates also remained relatively unchanged, the survey found.
Rs 37 lakh in Rs 2000 notes seized in Hyderabad
The officials seized a total of Rs 3.57 crore in cash from Karnataka and Goa, including Rs 2.93 in brand new notes. The entire unaccounted cash has been seized and further investigation is in progress, said IT officials.
High school seniors reported greater availability at 81 percent, but that was only a slight increase over last year's results, which were the lowest since the seniors were first asked the question back in 1975.
Ball said there's another possible danger when teens smoke cannabis every day. "And this risk is significantly higher for teen users than adult users".
In 2016, just over 38 percent of high school seniors living in states with medical marijuana laws reported past-year marijuana use, compared with just over 33 percent of seniors in states without these laws.
"We had predicted based on the changes in legalization, culture in the USA as well as decreasing perceptions among teenagers that marijuana was harmful that [accessibility and use] would go up". "Anecdotally in my life, I'd say that relationships between today's teens and their parents are also better than in past generations".
" Maybe marijuana use is becoming less and less a symbol of rebellion among teenagers", Nadelmann said. "But we haven't seen it", Volkow said.
In addition, the researchers found that marijuana use was more common among 12th graders who are living in states where medical marijuana is legal.
Unfortunately, e-cigarettes might counter these benefits.
"There's evidence emerging that nicotine can be a gateway drug", Volkow said. "As smoking in our country has gone down, that may have served to prevent the rewarding effects of other drugs". For 10th graders, the 2016 daily smoking rate is 2 percent, compared to 18 percent in 1996. That's down from just over 50 percent in the early 2000s, when the rate peaked.
Still, the main issue with e-cigarettes is the possibility they will lead to conventional cigarettes, explained Volkow. Some report not knowing what they are smoking.
