After generating $10.9 billion in global sales last year, the legal cannabis industry has the potential to expand to as much as $200 billion in yearly sales by 2030. That's an impressive growth rate we typically don't see reserved for "growing a plant."

But as investors, we also know that not every marijuana stock is going to be a winner. Even the brand-name pot stocks that have leaped to the front of the pack are not guaranteed to stay there.
