Police can use reasonable force to get a blood sample if the suspect refuses a chemical test. Your question is very vague and there is much more we'd need to know to answer completely.
Was the breath test a preliminary screening test or an "official" one? Was the person unable to complete two breath tests as required? Did the officers feel that the results of the breath test weren't matching up with their observations, making them suspect drugs as well?
Too much is missing from your question to answer accurately.
Most of the time the answer is yes .The police can make you submit to a blood test as well. The reason for a blood test is to search for drugs.I am concerned about the comment that your friend was held down and the blood was drawn. I don't have eough information on that question. Such as what was the charge or was there a search warrant.Under the general rule two blood alcohol tests does not give you a get out of jail free card.
