The Washington Poison Center has received 133 cases of marijuana exposures so far this year.

This is up from the 109 cases the center received at this time last year.

According to the Liquor Control Board’s Weekly Marijuana Dashboard, there are currently 161 retail stores reporting sales and an untold number of medical marijuana dispensaries estimated at over 1,000. “The increase in call volume on marijuana cases may be due to increased education efforts of community resources available to the public like the Poison Center and public education on what to do if someone is having a bad experience with marijuana,” says Dr. Garrard of the Washington Poison Center.

Significant increases in marijuana exposure are seen in users between 13 and 39 years of age, as well as 50 to 59 years of age.

There has also been an increase in exposures to children between 1 and 4 years of age.

Medical outcomes for the first half of 2015 show the majority of exposures resulting in minor effects (around 37 percent). These are symptoms that are considered minimally bothersome to patients.

23 percent of exposure cases had moderate effects on the marijuana user, and 3 percent of cases had a major effect.

9 percent of cases had no effect on the user.

There have been no deaths reported to the WAPC involving marijuana directly.

A little over half of the cases involved intentional use of marijuana, with abuse being the top reason for why the WAPC was contacted for help.
