The study, pooling data from seven North American studies, supports earlier findings and provides unambiguous evidence of the association.
A study examining Thailand's 'war on drugs' found that rural communities had a greater impact than urban centers, with 78% of rural users quitting injecting drugs. Despite the strictness of the policy, 85% of participants believed it was 'good', possibly due to its deterrent effect on others.
Researchers found that men and women who drank moderately but frequently had the lowest BMI scores, while infrequent heavy drinkers had the highest BMIs. The study suggests that drinking frequency and quantity can be important risk factors for obesity.
