I wish to gain some weight.is there a drug without side effect?

Diet and Exercise: The healthiest way to gain healthy weight is with healthy diet and exercise. If you eat fattening foods you might gain fat weight and spend the rest of your life trying to lose it. Fruits vegetables and reasonable servings of protein, like fish, meat, & cheese, and don't overdue bread, pasta, potatoes or rice. Plenty of water. Daily exercise without injury, anything you will do with enthusiasm.

Just Ask Alice....: There is no drug I know of that has no side effects,or that affects everyone the same.And there is no drug I know of that might stimulate your appetite that is completely safe either.I do know that legally obtained THC can stimulate the appetite,but its availability will depend on your state regulations and doctors who might prescribe it.I do guarantee that with enough exercise you'll get hungry
