I served the 7 day notice and was about to file an Unlawful Detainer, when she tells to me to "go ahead and waste your money, but you'll have to get permission from the bankruptcy court first".

If you do not respond to it you automatically lose the eviction, it stops the unlawful detainer action until it is settled.

If your lease contains a clause that no unlawful activity shall take place at the home then you're probably already covered since the legalization/decriminalization rules in pot friendly states only apply to small quantities anyway - if its a major grow operation or stash house then they are in violation.

“Drug-related illegal activity” means the illegal manufacture, sale, distribution, purchase, USE, or possession with intent to manufacture, sell distribute, or USE of a controlled substance (as defined in Section 102 or the Controlled Substance Act (21 U.S.C. 8002) or possession of drug paraphernalia.2.Resident, any member of the resident’s household or guest or other person under the resident’s control shall not engage in any act intended to facilitate illegal activity, including drug-related illegal activity, on or near the said premises.3.Resident or members of the household will not permit the dwelling to be used for, or to facilitate illegal activity, including drug-related illegal activity, regardless of whether the individual engaging in such activity is a member of the household.4.Resident or members of the household will not engage in the manufacture, sale or distribution of illegal drugs at any locations, whether on or near the dwelling unit premises, or otherwise.5.Resident, any members of the resident’s household, or a guest or other person under the resident’s control shall not engage in acts of violence, or threats of violence, including but not limited to the unlawful discharge of firearms, prostitution, criminal street gang activity, intimidation, or any other breach of the housing agreement that the other wise jeopardizes the health safety or welfare of the landlord, his agents, or tenants.6.VIOLATION OF THE ABOVE PROVISIONS SHALL BE A MATERIAL VIOLATION OF THE HOUSING AGREEMENT AND GOOD CAUSE FOR TEMINATION OF TENANCY.

In MD you would file for "Unlawful detainer" this is a similar to an eviction but different process.

A tenant’s guest shoots and kills someone at the rental property.Another tenant threatens to behead the landlord.And a third renter runs a prostitution ring out of the unit.In each case, the landlord pursues an eviction, and each time, the judge says no.These are just some of the eviction-worthy situations that have gone nowhere since April 6, when the California Judicial Council suspended virtually all unlawful-detainer proceedings in the state.In the cases above, the landlords pointed to the Judicial Council’s exception for threats to health and safety.The plaintiffs were still denied.The justification?

Further I have seen public records onapplicants whose report said no evictions found, but public court records showed 11 court actions within the past 13 months for  "warrant in debt" or "unlawful detainer", but no convictions because tenant paid before the court date. 

A court could look at this as an unlawful attempt to evict.

And you'll have the 'unlawful tenants' sue you for all you're worth for harassment .

The dictionary definition of a squatter is "a person who unlawfully occupies an uninhabited building or unused land".You have something known as "squatter's rights" (or adverse possession) which is: "A squatter's right is a legal allowance to use the property of another in the absence of an attempt by the owner to force eviction."
