Recreational cannabis use studies show that N3 sleep is affected, reports MDLinx.

“A lot of patients—as many as two-thirds in some studies—who are trying to quit recreational use [eventually] go back to smoking weed,” Dr. Kolla says. “Once they’ve stopped, their sleep is disturbed and they think, ‘If I go back to smoking weed, I can maybe sleep better.’ But cannabis changes sleep to a degree where users are more or less dependent on it.”
