An antibody is a Y-shaped four-chain protein with antigen-specific variable tips; opium poppy, cannabis, and coca plants each yield a narcotic/stimulant drug with characteristic health harms.
Antibody molecule (described, in place of a hand-drawn figure): An antibody (immunoglobulin) is Y-shaped, made of four polypeptide chains — two identical, longer 'heavy chains' and two identical, shorter 'light chains' — held together by disulfide bonds. Each arm of the Y has a variable region at its tip, which is the specific antigen-binding site (unique to each antibody, giving it specificity for one antigen), while the remainder of the chains form the constant region, which is similar across antibodies of the same class and determines the antibody's effector function (e.g., IgG, IgA, IgM, IgD, IgE classes).

(1) Papaver somniferum (opium poppy) — source of opioids such as morphine and heroin (smack). These are depressants that slow down body functions; adverse effects include drowsiness, respiratory depression, and strong physical addiction/dependence. …
