Surgeons widely gave opium (in the form of pills, powders, and an alcohol tincture of opium called laudanum), which gave relief to soldiers but often had hidden costs.
Each benefit was short-term; it had potent analgesia, slowed gut mobility, which was life-saving during dysentery, and it calmed cough
The harms were more long-term, the obvious being addiction or continuous use after discharge. Newspapers, physicians, and charities discussed the widespread post-war addiction
The Civil War expanded the demand for medical opium, boosting pharmacies and normalizing patent remedies. The growth of patent Medicines (some of which were opiate laced) fed a broader commercial market that outlived the war years.
Veterans facing addiction produced stigma and shame in families and communities as early media framed it as moral failure as much as illness. By the late 19th century, municipalities and reformers began restricting access while treatment clinics appeared in the 1890, foreshadowing later federal controls

Black troops often received less medical care overall, less opium was prescribed because of the stereotype that "Black People don't Feel Pain." When addiction did occur for Black Soldiers, it was not documented well, which made Black addiction experiences less visible to the public. Post-war, Black soldiers faced greater stigmas with opiate use but lower access to treatment. They did not receive the "gift" of opium the way their white counterparts did.

Women encountered Opium in popular tonics and syrups as well as in cultural portrayals, framing it as a "Gift." These items often contained dangerous opioid doses and were marketed heavily to an intended audience. In addition to the household, doctors frequently prescribed opium for "female Complaints", nerves, and pain, and were heavily targeted by patent medicine after the war. Some addictions in women stemmed from novels or magazines that romanticized the usage.

Confederate medical supplies were more inconsistent; many Confederate hospitals were short on opium by 1864. Doctors began to ration it or reserve it for amputations, which created uneven access based on rank, region, and supply lines.

White Union Soliders were often prescribed opium for pain and digestive illness but overall had better access due to better provisioning. However, their ability to have greater access and receive repeated doses led to dependency. In the Novel, Opium Slavery by Jonathan S. Jones, most opioid addiction cases are white veterans (partly because their records were better preserved.)
