For many people, 4:20 is a time that holds some significance. For those of us not down with the hippie lettuce, 4:20 comes and goes every day with no fanfare. Fact is, that time of day is no more noteworthy than, say, 1:15, 2:35 or 3:10. (Yes, the irony is not lost here, considering our fishwrap puts out a quarterly supplement called The Chronicle and has garnered reams of press for employing the first medical marijuana reviewer in the country.) Today, however, we'll be celebrating 4:20 by posting something special on the blog that smokers will appreciate -- particularly those into hip-hop. We got our hands on something we think you'll dig. At 4:20, we'll, ahem, dispense with what we have for you. In the meantime, carry on, and smoke 'em if you got 'em.
