What is it about?
The United States has been changing its laws to allow people to use cannabis for adults over the age of 21. This has led to studies that look at how many people are using cannabis and if it's causing problems. Most studies have focused on how many people are using it or if they have a problem using it too much. This study is different because it looks at how many people start using cannabis for the first time, and if it's happening more often in young people or older adults. The study used a big group of people from all over the country to get an idea of what's happening in different states. The researchers compared people who lived in states where the laws changed to allow cannabis use for adults to people who lived in states where it was still illegal. The study found that more older adults started using cannabis for the first time after the laws changed, but not more young people. This suggests that making cannabis legal to buy in stores might make more older people try it, but not more young people because they can't buy it legally. The researchers suggest that it might be more helpful to look at how many people start using cannabis for the first time, instead of just looking at how many people are using it. They also say that their methods of analysis are better than most methods used in the past.
