In general, yes. The great majority of Chupa Chups flavors are suitable for vegans. The majority of its constituents are fruit flavorings, colorings, and sugars. Milk products aren't used as ingredients of any kind. That said, there are three types of products that could contain animal by-products: triturated bones, which may contain small amounts of bone char; cellulose fibers obtained from wood pulp; and gelatin, which is derived from animal skin and bones. However, these items are present in such small quantities that they would not make a difference for the quality or nature of the product. For example, if you look on the package carefully, you will never find any mention of animals' products being used in Chupa Chups production. Instead, you will always see "made with sugar" or some similar phrase. Moreover, before eating any piece of candy, check to be sure it hasn't got any particles of cellulose fibers or gelatin in it. If so, then don't eat it. Otherwise, have fun! Of course, if you have an allergy to anything contained in Chupa Chups, then don't eat them. But unless you have an allergy, there's no reason why you shouldn't enjoy them.
