Has aspirin become illegal in Thailand?

I take 81mg aspirin per physician’s instruction after undergoing an angioplasty last year. 2 weeks ago, my spouse advised that he had to sign for the aspirin purchase based upon “a new law” that limits purchase of aspirin. Today at a discount pharmacy in Nonthaburi, he was told that aspirin was now illegal and we would have to go to the hospital to obtain. Say What? Is anyone aware of a new law that makes aspirin illegal?
Thanks!
