What are you defining as "better plays"? The whole segment is suspect. I mean, what legit biz would invest in an "industry" where the basic product is illegal at the federal level?
The whole thing is just nuts. They all trade on hype. There can be no industry so long as the feds are saying, "Well, today, right now, we aren't going to bust you. But that could all change tomorrow."
You can bet your a$$, if a bibly thumping conservative is elected pres while these laws are still on the books, it will all come crashing down, hard, very hard.
