How to monetize this Tumblr

I have a Tumblr blog:

• 2,000 followers
• all picture of weed
• average of 150 visitors a day (increasing)
• average time spent is 2 minutes

I can't use anything that prohibits "illicit" drug content. How do I make money from this blog?

I would most appreciate your help, guys. I will definitely return the favour.

hmm well im not TOO farmiliar with tumblr yet, but my suggestion would be to put up youtube videos of stoner songs onto your blog. Put a CPA PPD or w/e offer in the video in the description like 'download this song for ffree at' ppd link. if they have enough time to look at pictures of weed I don't see why they wont fill out a survey at a ppd website to download the song.

Try posters, mate of mine does great on his blog. Allposters has an alcohol & drug section
