Absolutely. Thank you.
Where that information comes from is observational data looking at different states in the U.S. Currently in the U.S. there are approximately 30 states where they have legalized medicinal cannabis. There are currently another eight states that have legalized recreational cannabis. They've been able to do some time-series analysis. They've looked in these states at the rate of use of different prescription medications before legalization of medicinal cannabis and then after.
Because this is an observational study, there could be other factors that are affecting the use of prescription drugs, but in a number of states they've shown this pattern that the rate of use of prescription drugs and the rate of purchase of these drugs have gone down for drugs typically used to treat chronic pain, anxiety and depression. This doesn't give us enough evidence to say that cannabis is effective in treating these conditions, but it's an interesting and promising observational signal that suggests there could be therapeutic benefit, and that in some cases patients may be substituting their pharmaceutical drugs in place of medicinal cannabis and finding sufficient relief that they are staying with that product.
