They can cause bad breath when eaten; and they can cause itchy or watery eyes while cutting and preparing them.

Aside from those two minor disadvantages; the benefits of onions are plentiful. They are notably rich in vitamins and minerals and have been used in the treatment of many variety of illness.

On a side note: Onions have gotten a lot of bad press for containing opium (or morphine). The reality however is that the opium in an onion is a very small trace amount; so small that it would take thousands of onions to even begin to create even a single dose that would have an effect on a human. It would also need to be extracted and prepared first, you could not eat enough volume of thousands of onions at once to ever reach the point where your body would react to an onion the way it reacts to a dosage of opium at a drug level.
