Reasons why marijuana wont be legalized that fast

I see there are some weed lovers in Steemit, and I have noticed, that most of them are from USA, where weed is allowed (I guess most states)
But below I will give some reasons why marijuana wont be legalized that fast in other countries (Europe)

• Tobacco industry is too big, they have a lot of money and power, they will protest that in multiple ways, because that would mean tobacco sales would decrease.
• Old people wont understand, when they were younger, in the world they were living, they were teached that it's very bad, and not acceptable.
• Big pharmacy companies will see a huge decrease in sales, since a lot of small issues can be treated with marijuana.
• People are not that educated around this topic, because there are still high standing people that have no clue about this, that's why they are saying it's bad for you.
• Some doctors are still in conflict of picking a decision if it's good or not. Most of them say bad, since saying okay could cost them their reputation.
