Weed is stronger and more accessible than ever, and addiction to it is rising, especially in young Americans, experts are warning.

Chris Pollock, 39, spent about five years as a director at a Southern California substance abuse treatment program, where he noticed a significant number of young adults, aged 18 to 25, resorting to marijuana to manage stress and sleep issues.

He explained to DailyMail.com that these individuals often become highly reliant on the drug. “Without marijuana, their ability to cope with anxiety diminishes, making it necessary for day-to-day functioning,” Pollock stated.

It is estimated that in 2022, 44 percent of young adults aged 19 to 30, or approximately 25.3 million individuals, used marijuana. This shows a notable increase from 28 percent in 2012.

Research indicates that there is about a 30 percent likelihood of becoming addicted to marijuana. Signs of addiction can include difficulty in limiting use, persistent cravings, and issues in personal relationships. Withdrawal symptoms may involve a decrease in appetite, difficulties with sleep, mood changes, and, in more severe instances, uncontrollable vomiting.

According to the National Institute on Drug Abuse, approximately 2.7million Americans meet the criteria for marijuana use disorder.

The increasing potency of marijuana might contribute to its addictive potential. Psychiatrist Ryan Sultan, who focuses on substance use, explained that marijuana products have been deliberately made stronger over time.

He remarked to DailyMail.com, “The marketing angle often emphasizes making marijuana as potent as possible. With increased strength, the potential for addiction inevitably rises.”

Pollock added: ‘Kids grew up with the idea from parents and [others] that weed is a very bad substance; it’s illegal and you can’t engage in it. All of a sudden, they’re seeing it’s legal with weed shops on every corner.’ 

Marijuana is illegal at the federal level and fully legal in 24 states, plus Washington DC. More than half of Americans live in states where recreational marijuana is legal, and 79 percent live in a county with at least one dispensary, according to the Pew Research Center. 

A typical dispensary sells ‘pre-rolls’, such as joints and blunts, as well as gummies and edibles. Dozens of strains are available from $25.

The content of THC, the psychoactive ingredient that makes one ‘high’ after consuming marijuana, in most strains is around 20 to 30 percent. 

This is a significant rise in THC content from 1995, when the average batch of marijuana seized by the DEA had a THC content of four percent. 

Sultan said: ‘An old joint would have a little bit of weed, like a skinny, little coffee straw, and now we have these massive, enormous joints.’

In weed pens and vapes, THC can reach percentages in the 90s. They are normally available for $50 to $100. 

Pollock said: ‘Weed pens make it very convenient. They reduce the amount of smell quite a bit, so even in school or at work, it’s very easy to hide it in comparison to other addictive substances such as alcohol, where it is much more apparent that someone is actively under the influence.’

Sultan is also concerned about the pens and vapes, as they are part of a trend of marijuana products designed for faster, easier consumption, with weed at its strongest levels.

In the US, marijuana is illegal at the federal level, classified as Schedule 1, putting it in the same class as heroin and ecstasy.

President Donald Trump said in August that he was ‘looking’ at reclassifying the drug: ‘Some people like it, some people hate it. Some people hate the whole concept of marijuana because if it does bad for the children, it does bad for people that are older than children.

‘It’s a very complicated subject, the subject of marijuana. I’ve heard great things having to do with medical and I’ve heard bad things having to do with just about everything else.’

Joe Biden’s administration proposed moving marijuana to a Schedule 3 drug last May. A Schedule 3 drug, such as ketamine or testosterone, has ‘moderate to low potential for physical and psychological dependence.’

Sultan, however, believes there should be more oversight around weed, especially its source. 

Weed grown illegally can be contaminated with pesticides or other toxic ingredients.

He said: ‘It’s gone from a boutique hobby to organizations that are trying to make money. There’s very little regulation or enforcement of regulation around quality [of] ingredients, whether the label is accurate or looking for pesticides. It’s supposed to all be tested but a lot of the testing is a little bit of a joke.’

Last year, the Los Angeles Times found that ‘more than half of cannabis smoking products in California’s legal market contain chemicals for which there is no public safety monitoring.’

There were 2,022 cases of vape product-related lung injuries reported in January 2020, per the CDC. About 80 percent of patients reported using weed products, which were largely acquired from ‘informal sources’ such as dealers, online sellers or friends.

Looking ahead, Pollock and Sultan believe there need to be drastic changes to the industry.

Sultan added: ‘If science was in charge of the laws, which we never have been, we would pretty clearly say that no one should be using under the age of 25.’
