Mezcal is more potent than tequila
There is more myth and legend pedalled about mezcal than virtually any other drink barring absinthe. Mezcal refers to an alcoholic beverage produced in Mexico from the fermented juice of any variety of the agave plant. Just as cognac is brandy but not all brandy is cognac, all tequila is mezcal but not all mezcal is tequila. Tequila is just the most refined.
The worm has special properties
Mezcal is often exported containing a dead mariposa worm (which feeds on the agave plant) as a mark of authenticity. What began as a bid for credibility has become a marketing gimmick. The worm in the mezcal is much like the plastic things you used to find in cornflakes boxes. Some producers have even gone further than one worm and offer dos gusanos.
Mezcal is hallucinogenic
This confusion stems from the similarity of the words mezcal and the mescaline. The mescal cactus has absolutely no relation to the agave plant, apart from the fact that the Indians called the agave mezcal. The conquistadors called it "maguey". The mescal cactus or peyote plant is the source of peyote buttons which contain the hallucinogenic drug, mescaline. Aldous Huxley has a lot to answer for.
Tequila is made from a cactus
This stems from the mezcal/mescaline confusion. The agave plant is not a cactus. Botanically, it's from the amaryllidaceae family.

Tequila is the principal ingredient in the margarita. It's a truly classic cocktail, which unlike the daiquiri, doesn't lend itself to variation. But no matter -- the basic margarita needs no improving.
The Basic Margarita
lemon or lime rind
salt for the glass
60ml of tequila
15ml of Cointreau
1 teaspoon of freshly squeezed lemon or lime juice
Rub rim of cocktail glass with the rind of the lemon or lime. Dip the glass rim down in the salt. Combine the rest of the ingredients and ice in a shaker and strain into the salt-rimmed glass. Put on anything by Herb Albert and the Tijuana Brass and put everything off until manyana.
Los tres cuates or the tequila slammer
The slammer uses the same time-honoured trinity of tequila, salt and lemon or lime that the margarita relies on, albeit in a more basic form. It's best with white or silver tequila. Participants lick a pinch of salt on the back of their hand, take a slug of tequila and then suck on a lemon or lime. It's a riot in the mouth. When you can no longer coordinate your lick sip suck, it's time to stop.
