In a daring undercover investigation, anti-marijuana activist Lisa Silverman has exposed the seedy criminal underworld that lurks along the lawn at a Ziggy Marley show:

In August, Silverman attended a Ziggy Marley concert at the Del Mar Racetrack, just as she had the previous year, to see if pot smokers were as abundant as before. Sure enough, bongs, blunts and joints were ablaze.

Actually, when the pot-smokers said "You want something, lady?" they weren’t really offering her a hit, they just wanted to know why she was crawling around on all fours sniffing people’s belongings and blowing out their matches.

"There were very few attendees who were not smoking marijuana," Silverman said, recounting her reconnaissance mission recently to a stunned board of directors for the fairgrounds.

The board of directors was indeed stunned by Silverman’s story, given that they’d posted signs at every entrance reminding security not to let the notorious complainer and buzzkill, Lisa Silverman, into any more reggae concerts.

At a recent concert at the Cricket Wireless Amphitheatre in Chula Vista, hip-hop superstar Snoop Dogg concluded his set by urging listeners to "smoke some chronic," slang for high-grade marijuana.

"Almost immediately, you could see the plumes of smoke go up," Kelly said.

San Diego songwriter Steve Poltz said he remembers attending an outdoor concert featuring James Taylor when the mellow superstar caught a whiff of marijuana smoke.

"Ah, yes," Taylor mused. "The fine scent of herb being carried on the evening zephyr."

At which point someone shouted "Dork!" and Taylor was struck with a flying beer can, proving yet again why people shouldn’t be allowed to use marijuana in public.
