It's a common misconception that pencil lead is or has ever been constituted of the element lead. It's true that thousands of years ago the element lead was formed into cylinders and used to make marks on papyrus, however, wooden pencils or any instrument since does not use lead (lead is a heavy metal and using pure lead in form can cause major health problems with extended exposure). Pencils now are made of graphite or some other pigment. However, graphite in solid form was discovered in the 16th century and at the time was thought to be some type of lead, which is why many people today still call pencil lead: lead.

When did they stop using lead in pencils?
Pencils were never made with lead, they have always been made with graphite. When pencils were first made it was beleived that graphite was a type of lead, but science has now proven graphite is a type of carbon, not lead. Well, i didn't want to delete this person's answer, but it is wrong. In fact, lead was used in pencils for hundreds of years, but there was a major problem with using lead. These pencils would form lead oxide on the tips, making it difficult to write, so when people wanted to write, they would lick the lead of the pencil to get the lead oxide off. When people realized that this was dangerous because consuming lead (even in minute quantities) can cause brain damage, pencils began to be manufactured with graphite instead of lead. Coming back to your original question - I don't know when they switched to graphite, but I think that it was sometime in the first half of the 20th century.
