Definition
In legal usage, **dram** means an alcoholic drink or a measure of intoxicating liquor. The term appears almost exclusively in two legal contexts:
1. **As a unit of measurement**: A small quantity of liquid, historically tied to apothecaries' and avoirdupois weight systems. In this sense, a dram is a precise, standard measure.
2. **As a colloquial unit of alcohol**: In common parlance adopted into law, a dram means any drink of a substance containing alcohol — something capable of producing intoxication. Courts have treated the term broadly, not requiring that the quantity be technically one dram in weight. Under this meaning, the term captures any serving of liquor sold or furnished to a person.
The second meaning is by far the dominant legal usage and is the root of **dram shop** law — the body of tort and statutory law governing liability for the sale or furnishing of alcoholic beverages.
**Dram shop** (also **dram-shop**): A place where intoxicating liquors are sold to be consumed on the premises; a drinking saloon or tavern. The term is now largely historical in ordinary speech, but survives robustly in legal usage as the name for the category of law regulating liquor-seller liability.

Common Language
**Modern common usage (Wiktionary)**: A small unit of weight — one sixteenth of an ounce avoirdupois (approximately 1.77 g) or one eighth of an ounce apothecary (approximately 3.89 g). Also used loosely to mean a small drink of spirits.
**Historical common usage (Webster's 1913)**: A unit of weight in both apothecaries' and avoirdupois systems; also "as much spirituous liquor as is usually drunk at once," as in a dram of brandy. In ordinary usage, the quantity sense was already sliding toward the colloquial sense of any small drink.
The gap between common and legal meaning is narrow in one direction and significant in another. Common usage preserves the weight-measurement meaning that legal usage has almost entirely abandoned. In law, **dram** is not a precise quantity at all — it means any intoxicating drink, regardless of volume or measure. A researcher encountering "dram" in a legal document should resist the weight-measurement meaning entirely and read it as a reference to alcoholic liquor generally.

Common Confusion
**Dram** vs. **drachm**: These are variant spellings of the same unit of weight and are interchangeable in pharmacological and historical contexts. In legal documents, however, "dram" almost never refers to the weight unit — it refers to liquor. Do not import the precision of the pharmacological meaning into liquor-liability statutes or case law.
**Dram shop** vs. **tavern/saloon/bar**: These terms overlap substantially but are not synonymous in legal research. "Dram shop" in statutory law is a term of art identifying the regulated category of alcohol vendor. Modern dram shop acts may extend liability to establishments not historically called dram shops (social hosts, restaurants), while the label "dram shop" in older sources refers specifically to on-premises liquor sellers.

Why It Matters in Research
The term's primary research value lies in its role as the root of **dram shop acts** — statutes imposing civil (and sometimes criminal) liability on sellers or furnishers of alcohol for injuries caused by intoxicated persons to whom they sold or served liquor. These statutes vary dramatically by jurisdiction in scope, defendant class, causation standards, and damage caps.
**Trap for historical researchers**: In nineteenth- and early-twentieth-century sources, "dram shop" is the standard label for what modern statutes and cases call "liquor liability" or "alcohol vendor liability." A researcher using only modern search terms will miss substantial historical case law indexed under dram shop, tippling house, and saloon keeper liability.
**Trap for modern researchers**: Many states have repealed standalone dram shop acts and folded liability into general negligence or their liquor control statutes. The label "dram shop act" may not appear in the controlling authority even when the legal theory is identical. Check whether your jurisdiction's liquor liability law is statutory or common-law based — the distinction affects defenses, damage caps, and who qualifies as a plaintiff.
**Corpus connection**: Dram shop cases frequently connect to negligence per se doctrine (where violation of a liquor control statute establishes the standard of care), proximate causation disputes (intervening act of the intoxicated person), and wrongful death claims. Researchers should pull the Torts encyclopedia entry (torts_47) as a navigational anchor before diving into jurisdiction-specific case law.

Historical Dictionary Support
The historical dictionaries converge on a simple, functional definition: a dram is an alcoholic drink, something capable of intoxication. All four sources agree on this core meaning, though none elaborate extensively.
Black's (2nd Ed.) is the most useful of the shelf sources here. It supplies the dram-shop definition with case citations — Wright v. People and Brockway v. State — confirming that the dram shop as a legal category was well established by the late nineteenth century across multiple jurisdictions. Bouvier's cites Texas authority (32 Tex. 228) for the intoxication-capable meaning, consistent with Black's citation to the same case (Lacy v. State).
What the historical dictionaries miss: they do not capture the statutory evolution. By the time Black's 2nd Ed. was published, several states had enacted formal dram shop acts imposing statutory liability on sellers. The dictionary definitions treat "dram shop" descriptively (a place where liquor is sold on-premises) without flagging the regulatory and tort-liability framework that was already developing around the term. Researchers using historical dictionaries alone will get the vocabulary but not the law.

Jurisdictional Note
Dram shop liability is entirely a matter of state law; there is no federal dram shop statute. Approximately forty states have some form of statutory or common-law dram shop liability, but the scope, covered defendants, causation requirements, and available defenses differ substantially. A minority of states impose no third-party liability on commercial alcohol vendors.
