Salem, OR -

Some Oregon lawmakers feared that allowing medical marijuana cardholders to use pot for post-traumatic stress disorder would lead to widespread abuse.

But the Oregon Health Authority tells the Salem Statesman Journal that fewer than 100 people have cited PTSD in applying for cards. The agency says the number is so low that it risks identifying specific patients if it reveals exactly how many.

Republican Sen. Brian Boquist of Dallas co-sponsored the bill last year that put Oregon among the few states that allow medical marijuana for PTSD.

He says several of his constituents who are veterans asked for the provision. Boquist says he never thought that many people would use it.

The law was effective Jan. 1, but people with PTSD had 90 days before that to submit applications.
