I felt amphetamine has entactogen-like effects, before even knowing that they were closely related; imagine what someone knowingly ingesting amphetamine as an entactogen might feel. Why are many entheogens and entactogens illegal if they have many benefits and miniscule possible harm? Well, the short answer is for no reason.
Dislocated shoulder. A dislocated shoulder happens when your upper arm pops out of your shoulder socket. The shoulder is one of the easiest joints to dislocate because the ball joint of your upper arm sits in a very shallow socket. This makes the arm extremely mobile and able to move in many directions, but also means it isn't very stable.
Wearing a shoulder dislocation sling is an excellent way to treat this type of injury. Patients who have suffered a dislocated shoulder need to seek medical attention immediately. And you have to consider that using arm slings for shoulder alone may not fix the dislocation problem, and surgery may be required.
