The simple answer is yes, checked bags can be searched for drugs. However, there are a few things to keep in mind. First, the TSA (Transportation Security Administration) is primarily concerned with terrorism and security threats, so they are not specifically looking for drugs. Second, the TSA does not have the authority to search bags for drugs unless there is reason to believe that a crime has been committed. So, if you are carrying drugs in your checked bag, it is possible that your bag will be searched. However, it is unlikely that you will be targeted for a search simply because you are carrying drugs.
