Sharon Stone 'Pretty Sick' for a Month After Quitting Weed.

Sharon Stone has a warning for anyone who still thinks of marijuana as the same drug it was decades ago.

“It’s not like when we were kids.”

Stone told Variety that she decided to quit smoking pot as part of an effort to live drug-free. She became “pretty sick” for a month—sick enough to visit her neurologist.

Her experience prompted Fox News to examine the risks posed by today’s high-potency marijuana.

Stone didn’t describe her exact symptoms, so her experience can’t be medically diagnosed from an interview. But the larger warning is real.

Marijuana has become much stronger.

The CDC says the average THC concentration in research samples rose from 9 percent in 2008 to 17 percent in 2017. One study of dispensary products found an average of 22 percent, with some reaching 45 percent. Concentrates can go much higher.

Regular users who quit can experience insomnia, anxiety, irritability, appetite loss, sweating, headaches and nausea.

America spent years debating whether to legalize the marijuana people remembered.

What’s being sold today can be a much stronger drug.
