Ever notice how guys who smoke a lot of pot also tend to get laid a lot? I'm not necessarily advocating smoking weed just to get girls, but I have found that it makes it super easy to get girls back to your place. I will elaborate:

Adventure - Some girls may seek a thrill. When you say to a girl “Hey, want to go back to my place and smoke?” you are basically asking her to go on a little adventure with you. It’s a little taboo, but not anything dangerous or too crazy. It’s not something most girls do everyday, but might be an interesting little break from her typical night out for drinks. In other words, it can lead to fun times.

Ease of mind - A girls will often flake on a guy or flat out say no when a guy asks a girl to hangout. This is because it might be awkward, or boring, or whatever other stupid reason they might have in their brain. As guys, we don’t care about this kind of stuff because guys are more concerned with getting laid; we don’t care if it might be awkward. For many girls, smoking weed automatically eliminates any worries of awkwardness, anxiety, or boredom. Many girls view pot smokers as laid back, relaxed, and more open to conversations than more conservative individuals. Pot also allows some people to express themselves much more freely. Many perceive pot smokers as generally very cool and nonviolent, which further adds comfort to the situation.

Plausible deniability - It is a predefined activity that gives a purpose for her to come back to your place with you. Girls often times want to go home with guys, but do not feel comfortable doing so unless they have a more “innocent” excuse. You can ask a girl back to your place for drinks, movies, coffee, etc., but girls can do this stuff anywhere, any time they want. Going back to your place to smoke is the ultimate plausible deniability. A girl is much more comfortable saying yes to this than any other excuse I have heard guys use to bring a girl back.

The hookup - For a guy and a girl to get stoned together - this is a great experience that can easily lead to a romantic fling. It is a great opportunity for kino and escalating. And since she’s already back at your place, there’s no reason why she can’t spend the night ;)

I am not trying to glorify pot in any way, or advocate its use. Personally, I don’t even consider myself a regular pot smoker. I just use it to make girls more comfortable in certain situations. It’s simply a great way to get girls back to your place from a bar, club, party, etc. It has actually worked wonders for me. It’s just like asking a girl back to your place for drinks, just with a much higher success rate.
