The lobby smells money?

Within the last 20 years there has never been a higher interest in Cannabis than nowadays, but why now and why does the lobby starts to push the industry suddenly? Do they want to make the world a better place or do they simply smell the money? 

There are many questions regarding this topic as since Coca Cola announced that they are interested in entering the market is is no longer a big secret that this industry will grow massivly within the next years and what does our lobby...no they won't just be at the sideline and watch.

I remember that 15 years ago no one really spoke about this topic or even thought about to buy cannabis stocks, the politics were mostly against it and declared it as a drug. Now let us jump back to the present time, my conservative dad owns cannabis stocks and talks about them with me, our politicians want to legalize cannabis quicker than the other countries it and push it thourgh all instances so qucik as it was never seen before, just because they want to make the world better with their actions...?

In my opinion this all happens as the big boys and our lobby knows there is a lot of money in this industry so they simple make everything they need to make sure they profit enough from it, or what is your opinion in this topic?
