I recall a story about how when MAPS was going through the initial process of starting trials, they were permitted to introduce evidence of the safety from times when it was illegal, which also provided a bit of long term results. More recently when asked about the safety, MAPS states that the dosages and frequency being used are below what is known to cause problems. Now they are entering phase 3, which will be large scale.
