— It’s known as Mary Jane, ganja, Chronic and even the sticky icky and has been featured in countless movies, including one that warned of its dangers, “Reefer Madness.”

Now, marijuana is the subject of a contemporary history and science exhibit.

“Altered State: Marijuana in California,” a one-of-its-kind museum exhibition focusing on the topic, is open through the summer at the Oakland Museum of California.

Set against the backdrop of a California ballot measure this year asking voters to legalize marijuana’s recreational use, the exhibition features artwork, political documents and posters, and scientific and interactive displays meant to provoke questions and conversations about pot.

The exhibit comes when 35 states already have medical marijuana laws on the books and four states and Washington, D.C., have legalized weed for recreational use.

PHILADELPHIA — The Museum of the American Revolution in Philadelphia has announced it will open on April 19 next year. It’s the anniversary of the opening battles in 1775 between British troops and American colonists in Lexington and Concord and the “shot heard round the world.”

One of the marquee exhibits will be Gen. George Washington’s headquarters tent during the Valley Forge winter of 1777-78. It will be viewable through a glass wall and in a completely sealed environment.

The museum has built up a large collection, including guns and other artifacts from the first fighting of the Revolutionary War.
