Marijuana normalizes sleep efficiency in marijuana-dependent volunteers

high school age persons, 31.0% [p<0.0001] and 31.2% [p≤0.0002], respectively. Population and URDD rates for amphetamines were higher for college age persons, 35.5% [p<0.0001] and 35.6% [p<0.0001], respectively. Conclusions: Results show seasonal trends for stimulant use: for both high school and college age groups, Intentional Misuse and Abuse rates were 25% higher in school months compared to summer months. Also, rates for two classes of stimulants were different; college age showed higher rates of amphetamine use, while high school age showed higher rates of methylphenidate use.
