What’s the bust advertising platform

Please can someone help me with the best advertising platforms, I do own a website, telegram channel which I sell premium quality cannabis and psychedelic products and I’m looking for a good advertising platform that’s not expensive for advertising and driving traffic to my telegram channel (under the mentioned Niche)

I was about to say google ads for search and Facebook ads for social media but I don't think they allow cannabis.
You have to search ad platform that allows cannabis.

It is risky because of some legal issues, look into specialized platforms like Weedmaps or Leafly. You can also try social media platforms like Instagram or Reddit, but be sure to follow their rules that's important
