Short answer. Yes. Drug addiction or habitual alcoholism of the respondent is the fifth ground for legal separation, and unlike the annulment provisions it does not matter when the problem began. What has to be shown is addiction or habituality, not occasional use.

It does not matter that it started after the wedding
This is the difference that sends most people to this ground rather than to annulment. Concealment of drug addiction or habitual alcoholism can support an annulment case, but only where the condition already existed at the time of the marriage and was hidden from you. The legal separation clause carries no such limit. It asks about the respondent's condition, not about what was true on the wedding day, so a dependency that developed in year eight of the marriage is squarely within it.
Addiction and habituality, not use
The words chosen are Drug addiction or habitual alcoholism, and both carry a threshold. Drinking that is heavy at times, or drug use on occasions, is not what the clause describes; it is aimed at a settled condition that has taken hold of how your spouse lives. What tends to establish it is the pattern and its consequences over time — employment lost, money gone, treatment sought or refused, the household organised around it — rather than any single episode, however bad that episode was.
What the decree will and will not fix
A decree of legal separation ends the obligation to live together and dissolves the property regime, which is often the practical point where a dependency is draining the family's money. It does not end the marriage, and neither spouse becomes free to marry again. Nor does it stop the conduct. If the addiction comes with violence, that is a separate ground in its own right and there are protective remedies that act much faster than this case can.
Build the record, and know the bars
Useful proof is the ordinary evidence of a life: treatment or rehabilitation records, hospital admissions, employment records, bank and remittance history, messages, and people who have watched it happen. Be candid with a lawyer about the whole history, including any period when you forgave what happened and carried on, because the Family Code separately bars relief where the aggrieved spouse condoned or consented to the conduct complained of, or where the action has already prescribed.
