Have we missed the boat on BDA/and or others

I recently saw a random news piece about the legalization of Marijuana in California and decided to take a look as well as the emerging medical marijuana sector in Aus I am a complete noob when it comes to Marijuana and I think this may come across as a silly question.

Just to let anyone know my modest portfolio consists of tech and lithium and im looking to diversify. But have I  missed the boat on BDA as well as a few Cannabis stocks which i won't name? or is this just the beginning? Please give informed opinions.


[Just to let everyone know im reading up on BDA and the sector as I write this and learning. Also please be kind im new}
