New research from Northeastern University finds that regular marijuana use suppresses the effects of Adderall on the brains of mice - Northeastern University College of Science

Adderall is prescribed for attention deficit disorders as a way to help focus.

Marijuana is legal in two dozen states and is used by many to relax.

New research from Northeastern University says you shouldn’t use the two in combination — finding that regular marijuana use suppresses the effects of Adderall on the brains of mice.

The research was conducted at the Center for Translational Neuroimagery at Northeastern, an MRI lab run by psychology professor Craig Ferris, and it was published in the journal Frontiers of Pharmacology.

The study involved two groups of mice.

The first group acted as a control, while the second group was exposed to vaporized cannabis for 30 minutes a day for 10 straight days. The daily exposure was enough to achieve blood levels of THC — the active ingredient that produces the psychoactive effect in cannabis — comparable to those recorded by humans.
