Even if smoking increases, there are intriguing suggestions that this means drinking will decline. That change alone could have a huge impact on public health. “The social costs of alcohol are pretty darn high,” said D. Mark Anderson, an economist at Montana State University who has conducted several studies on public health and marijuana policy. His own research suggests that alcohol and marijuana are substitutes for each other, not complements: in other words, if marijuana becomes easier to acquire, people may use it instead of alcohol, not on top of it. “If the substitution effect is large, then increasing marijuana consumption could really provide public health benefits,” Anderson said in an interview.

Though some lab experiments have suggested that people under the influence of THC, marijuana’s psychoactive component, are likelier than drunk people to overestimate the degree to which they are impaired and take more precautionary measures, such …read more
