Aside from cocaine, Love is the drug that the Seventies ran on.
At least, that’s how the legend runs. (And hey, the legend gave us Rumours, so clearly there’s something to it.) In practice, it was a lot more like Lust, or perhaps Sex Addiction.
Unlike the majority of other drugs I’ve listed here, Love has the advantage of being street legal – although like most drugs, you should still exercise some caution in when, where and with whom you choose to indulge 😉
