House and Senate lawmakers delivered a state budget to Governor Deval Patrick on Thursday that loosens a ban on gifts from drug companies to doctors, tightens rules for welfare recipients, and includes provisions to crack down on illegal immigrants.

The bill reflects the melding of earlier versions of the budget passed by the House and Senate and will be subject to possible vetoes by Patrick. The governor’s budget chief, Jay Gonzalez, released a statement praising lawmakers for approving changes Patrick had sought in the oversight of community colleges, but saying the rest remains under review.
