The word 'Zigarette' (cigarette) comes from French, and the ending '-ette' is a diminutive form. So a cigarette is literally a 'small cigar'.
Er raucht lieber Zigarren, keine Zigaretten.
He prefers smoking cigars, not cigarettes.
Common verbs describe the whole process: you light a cigarette, smoke it, and put it out at the end.
Kannst du mir Feuer geben, um meine Zigarette anzuzünden?

The colloquial phrase 'eine rauchen gehen' means to take a break in order to smoke a cigarette. It is often used as a suggestion or announcement.
Ich gehe kurz vor die Tür eine rauchen.

Cigarettes are often bought or mentioned in specific quantities. Typical units are 'eine Schachtel Zigaretten' (a pack of cigarettes, usually about 20) or 'eine Stange Zigaretten' (a carton of cigarettes, usually 10 packs).
Könntest du mir vom Supermarkt eine Schachtel Zigaretten mitbringen?
Could you bring me a pack of cigarettes from the supermarket?
joint
'Zigarette' and 'Joint' both refer to something rolled that you smoke. The important difference is the contents. A 'Zigarette' contains tobacco and is usually industrially made or hand-rolled. A 'Joint' is a hand-rolled cigarette with cannabis. Learners may confuse the words because a joint can look like a cigarette in shape. Still, 'Joint' is much more specific and refers to cannabis. If only tobacco is meant, you say 'Zigarette'.

A man is smoking a cigarette in front of the train station.
In dem Film sitzt die Gruppe im Park und raucht einen Joint.
In the film, the group is sitting in the park and smoking a joint.
