Explanation
The Joke
One person says to another: "Baby, your love is like heroin to me." The other person starts to respond warmly with "Aww, that's--" but is cut off by the first person completing the thought: "I'm quitting you now that I have methadone."
The Humor
The joke takes the classic romantic cliche of comparing love to a drug -- usually meant to convey passion, intensity, and addictiveness -- and follows the metaphor to its most unromantic conclusion. If someone's love really is like heroin, then the logical next step is to seek treatment to get off it. Methadone is a medication used to help people recover from opioid addiction by reducing withdrawal symptoms and cravings.
So instead of the comparison being flattering ("your love is so intoxicating"), it becomes a breakup line: the speaker has found a pharmaceutical substitute that lets them quit the relationship. The humor lies in the bait-and-switch -- the listener expects a romantic declaration but instead gets dumped via an extended drug metaphor.
