Cannabis is now basically legal, in the right states. You just need a license to sell it. Once you have your license, you should list yourself on good-weed.com.
Listing yourself on https://good-weed.com is immediate and free, and lets people find you and your local cannabis service.
If you don't yet have a license to sell cannabis, you can still sell paraphernalia: rolling papers, lighters, ashtrays, bongs, entertainment materials, and art.
Make sure to give excellent customer service, get good reviews and ratings, and rise to the top of the ranked sellers in your area.
To happy high times and business :)
