The FDA classified genetically modified foods as "substantially equivalent" to non-GMO foods. They do not have to pass human testing prior to being produced and sold to consumers or at any other time.

The only proven disadvantage to genetically modified (GM) crops is that some people have shown an alleregic reaction.
It really depends what type of genetically modified crop it is
Genetically modified crops are crops with plants that have been genetically altered in order to increase the yield of the crop. For example, the plant may have been genetically altered to become bigger or more resistant to bugs.

No, because the crops are just grown faster than normal.
Genetically modified foods are generally modified to accept/work with pesticides better. Monsanto makes a product called Round-Up and genetically modified foods are sometimes called Round-Up Ready crops. The downside to granting any company a monopoly over any foodstuff could be very serious. If you fail to buy the required pesticide product, you simply don't get to have as much food. And once these GM crops are in the fields, cross-contamination with other crops is unavoidable.
A lot of people are against genetically modified crops being grown because of potential negative health effects. The effects of altering crops genetically are also not known due to the process being relatively new.
