Buying stock in weed?

I missed my penny stock company Frontier Communications when it was .02 a share. Now it's .50 a share. Not a bad bump for someone who bought 500 bucks worth of it whe it was 2 cents! Sadly it wasn't me.....how does a huge telco company get down to .02 a share? No weed stock for me. When it's legal. It can be grown by anyone and its literally a weed, grows very well.
