420 refers to marijuana smoking, so '420 friendly' means that the person posting the profile either smokes pot, or, is open to dating someone that uses marijuana.Originally it was used as code amongst marijuana smokers.
Today, it's prevalent with pretty much anyone who uses marijuana, although more so in North America.
There are even 420 dating sites catering to people with this interest.
My420Mate call themselves the Cupids of Cannabis, which might be right seeing that they are currently number one dating site for cannabis users.
Even though that at first you might have thought this to be a hotspot for the typical lazy stoner that is looking for an equally clouded partner it is actually for both the recreational users of marijuana and the medical users as well.
This does not mean that you will find only stoners on their websites and in their apps; there are a lot of ways people like to enjoy their weed, some more frequent than others.
At least you will know that your next possible date (or person you just want to hang out with) will not make an issue of your cannabis use, you can be sure of that.
