Hi Genny and welcome to the forums. Salvia being used for spiritual use is certainly one of the arguments, but there are many more too. Have a look at the state by state legal watchdog area here. I am constantly updating it and there are example letters you can send in that address all the reasons that we could think of so far of why Salvia isn't suitable for scheduling. There are also links to the direct bill and links to the Michigan government website area to keep an eye on the bill. It also has links to look up your local legislators so you can see who you need to send a letter to. Here is the direct link...

I am keeping an eye on any upcoming public hearings and the more people we can get to attend the more of a chance that we can get this bill turned down. There are only a few people that intend on going so far that I know of so we need all the help we can get. Are you registered to vote? If not, go do it today so you can voice your opinion!
